good game

This game plays upon my specific fears of the deep ocean and being locked in a tiny space, which makes it perfect before-bed playing material. Every single aspect of this game was top notch from the sound design to the visuals. There wasn't a single scare that didn't get me. It took me a while to realise what I had to do (I didn't realise that the map is divided into quadrants which affect the co-ordinates on the display) but once I did I was on the edge of my seat!

From the moment I opened the game I never felt safe - the pacing here is phenominal. This is one of few games to make me feel genuine paranoia. I felt a constant need to keep my little sub moving, checking over my shoulder even though - as far as I could tell - I wasn't being chased by anything. I'd be surprised if there were actual enemies in the game to avoid. The sound design is so good that they could have just been suggested to me.

I was so glad to be done with the game that I almost missed the secret co-ordinates on the end credits screen...

Dare I wonder what they lead to?

Great game. I was very scared. It is like Subnautica but on ps1, and it is cursed

Incredible! I loved the ending. One question though, who's the person on the ''Ever dreamt this man'' pic? Lmaooo

Hi Kira, I made a video on why I think Corpse Ocean deserves just as much recognition as Iron Lung. Thank you for making such an interesting game.

This was a great game! I have a big fear of the ocean, so this was probably a bad idea to play it lol, but it was really fun!

You guys did it again 10/10 and will recommend. Here's my footage of gameplay if you're into that stuff ✌

gameplay starts at 16:10

This game boasts a fantastic atmosphere!  Unfortunately, I did not encounter any whales

(1 edit)

Really good atmosphere! Nice tension, I'm personally not that good at navigating after coordinates but it was oddly fun. I really like the ending although I think it's a bit expected to be a big monster or something like that at that point. Still really good 9/10 would recommend to a friend.

I didn't see any whales :(

Thanks for the amazing game! hope to see more games from you ^- ^


i swear the text font and background is familiar


I have Thalassophobia, so this was basically the worst idea I've ever had (aside from playing both Subnauticas). This legitimately terrified me! Staring into the infinite dark void of the deep is something that just makes my brain activate survival mode, so this game was hard to get through. But I did it, and it was fun! Definitely recommend if you like short horror games. Props to the developer!

somehow a sheap recognized the guy that after he gets out  he have no energy but somehow a sheap recognize him and then he never spoke about his accident

can t wait to play this  cool sick game i mean good job  whith the creativity i just ended playing it and what s is the faith of the pilot ddo he die  so if he didn t die i have a  continuing story for your game he bring the two oxygene bottle whith him and wear his swim suit and somehow he survived from that monster and now he have é hours to escape from the water dunjon

Loved it!!!

Pretty cool game! I appreciated it. 5 stars for you  Kira, again ;)

CorpseOcean - video

I loved this game once I figured it out! Great work, that ending was so cool! Timestamp is 06:15 if you're interested!

The Easter eggs at the end with Cords that lead you to taps is a very cool thing!

This game is really cool, my friend @pinworm loves your content and told me to play it. 10 Days, for this incredible, interesting, one of a kind, fun enticing game. Definitely going to look into it more games! I enjoyed it a lot! 7/10


This game was super awesome! As a game dev myself whenever I play a Kira game it always inspires me to work harder and this game was no exception I really loved the controls and being under the ocean was super freaky. Great job on this one Kira!


Brilliant! I've played The Undying Beast and thought that game was great, and somehow you've still managed to outdo yourself with this one. Loved it.


i guess im just too dumb for this cause i just found it too difficult to finish. 

I really enjoy the gameplay mechanics here. Controlling the sub and keeping up with the coordinates is very active and you don't get that a lot from other horror games. I'm not sure if it was just my playthrough in particular, but other than a couple tapes and the barrels, I didn't really come across much actually happening. I guess I'm just saying that it felt very empty to me. I still enjoyed it though. Thanks for making it!

This was just brimming with spookiness! Loved that it was continually getting darker after each find and that there were various spooks throughout! It felt very steady in terms of pacing, and the lore was top tier! Such a good job! 

Corpse Ocean is  dripping with atmosphere! It progresses at just the right pace, establishing a sense of serenity early on, only to subvert this as gameplay progresses. The scares are really well done and offer a nice mix of sudden, shocking moments with prolonged periods of dread. The change from spooky to normal, as well as a certain blink-and-you'll-miss-it moment, make you doubt your character's sanity, making the game feel thematically Lovecraftian. Great job!

Also, here's a link to my video. It's not a Let's Play, but rather a synopsis of my gameplay experience with my thoughts sprinkled throughout :)

Comments below clip;

There's something to being under water. At the surface of it, we're all OK. But, once you dive deeper, and feel the pressure and cold building up, you surely appreciate your submersible, no matter how small or big it is. 

This game had me going back and forth, on a journey to collect lost goods, and even dive below the specs that'll let me survive these depths.

Thank you for letting me enjoy 20 minutes of being in an entirely different world...

Kudos to all involved!

hi, big thx for the game. greetings from rosti 🙏😉


I love this

This is a very interesting ocean horror game! Though, I wonder how many VHS tapes there are within the waters. I only found a few so far.  


Check the game case for a hint to where they are 

Alright, I'll  do that. Thank you, Maple.

Man this one freaked me out. I need to watch a video of it now so I can see the ending better, but overall this was a smash success.

Not gonna lie, I came here to see the comment "dont rely on the sonar", realized I was bein a goof by not looking at the  coords lmao Good game once I figured it out and felt super dumb :)  Always love to see what KIRA does 

Full play No Commentary 

I find under the ocean to be absolutely terrifying. You did an incredible job at replicating that feeling of exploring its depths.

This was cool! I had a fun time diving beyond my craft's maximum depth allowance.

First, the bad: Could not tell what to do/where to go. Found a couple of tapes, explored the entire map, did not find anything of note. Had to eventually quit. Sonar does not appear to reliably lead you to any objects of interest. Really unfortunate, was greatly looking forward to this. I understand it was made quickly for a game jam though without much opportunity for play testing. 

If you continue working on this concept, some proposed additions:

1. Ambient atmospheric life support noises
2. A robot arm for collecting the tapes
3. The sonar monitor doubling as a down-facing video feed using one of the buttons, maybe some other views to toggle between (up, left, right, rear, opportunities for spoops to appear on the monitors when this is happening)
4. Finite but generous O2 supply which visibly dwindles over time to furnish constant low level anxiety
5. Finite battery which also dwindles as you use it up, see above
6. Ability to surface in order to replenish O2 and battery (from solar) on missions in shallow water, but not deep water missions
7. Drop weights (which can malfunction for a few spoop moments)
8. Increased variety of marine life (Obviously you did not have time for this, even the whale was nice though)

Having said all that, some well deserved praise: This control scheme rocks for a submersible game. Piloting the sub while simultaneously being able to look around inside it to operate the controls, I mean.  I'm shocked I haven't seen in done in any big budget games before.

It'd also work very well in VR, looking around with your head, reaching around to push buttons/flip switches with your own hands, some spoops happening *inside* the sub itself. Like when you turn around, after perhaps seeing a moving shadow on the wall of the sub to one side, or hallucinations where there's another bubble window behind you, very fertile concept for horror and very intuitive/capable mechanics! 

I would very much like to see this expanded into a full game with expanded mechanics and modernized visuals, especially if it supports VR. It's got a lot of untapped potential, there's nothing like it in the horror space to my knowledge. 

I wrote the in-game dialogue and consulted on marine technology details for Narcosis, a well received VR deep sea survival horror game, and would be happy to lend my talents to such a project if ever you felt inclined to move in that direction. 


Thanks for the feedback! Yeah using the coordinates to get to the barrels is the main objective, but some people use the sonar exclusively for some reason. The game does have a progression and an end, but without scanning the materials and following the coordinates it doesn't progress.

I think people use sonar initially, because they think it's a exploration horror game. Where the objects are hidden until they bump into it, like how slender the 8 pages was. Also I think some people don't realize their being given the coordinates under the tutorial prompts. I know it took me a few seconds to realize those were coordinates. 

Amazing game as usual though!! I know I loved it.
