Pretty neat game man. It kind of reminds me of Iron Lung which is always neat. Nice work :)

I really liked it.
It felt a little claustrophobic, in a good way.

Very fresh game, very moody! was really fun managing the different things like leaks and all. congrats!

It's a nice game, it gives me FNAF + Sea Of Thieves + Overcooked vibes. I really enjoyed it, the game kept me in a constant state of stress and fear that I might do something wrong (and that's good!).

However, there are a lot of problems I see and I hope this will help you understand my experience.

First of all, it was very hard to understand what to do in this game. Nobody reads huge manuals, so think about it, maybe some kind of AI should teach the player how to fix all the leaks in the beginning (like the AI in saubnautica). 

The next problem is that the player can't see how close he is to the end because all the progress bars have no background color. So I don't know where it ends. 

The next one - I don't understand what to do with water, I can't remove it like in Sea of Thieves... 

The next problem is that there is a huge problem with the in-game UI/UX - for example, vents are above filters, but the filter button is on the left, while vents are on the right (but we read things up-down, left-right, so the vents button should be first), and other screens can be better. 

I also got a red light at the end, and I don't know why, I didn't do anything wrong (I won anyway). The game also lacks background music or some sounds - alarm, enemy approaching, etc. Good sounds can help in creating the desired atmosphere.

Nevertheless, it's a good game and I really liked it. I'm giving it a high rating and I hope you'll improve it later!

Very interesting game idea! I like the visuals and atmosphere.  But аt first it is very difficult to understand what is what. But i still enjoyed it. Great job!

nice game the art style reminds me of liminal spaces and backrooms

I like the claustrophobic atmosphere (could be even more with a lower ceiling). The pace is good. I like the change of lights when there is an issue, and that water. Perhaps some hint on levels could helps, green(ok)/orange(warning)/red(imminent issue), and perhaps some alert sound on the monitor that trigger the issue, of some bulb light that blink.
Cool game, I had fun playing it ! 

Really nice vibe! Gameplay seems solid, but it wasn't always clear what I was dying to on some runs. Perhaps an it needs an audio announcement of the system that needs fixing? Great job!

Very cool idea and fits the theme perfectly! Had a blast playing it. Definitely nailed the claustrophobic vibes of being stuck inside a submarine as things start to go out of control. Very cool!

Really cool vibe and lighting! Felt like I was really in a sub trying to stop my own doom (I did not haha)

Cool game, great interpretation of the theme!
Imho the engine can break a bit more often, for me it happened just 2 times so I didn't have to monitor air purity at all

Pretty cool game! Although I died because I ran out of oxygen, and I wasn't sure how to stop that from happening. maybe a tutorial would have been helpful. Otherwise, great work, definitely enjoyed playing

Very cool game! Still trying to survive, so wish me luck :)

Wow, very impressive! We actually had a very similar idea to this game, but decided not to go with it. That's probably a good thing because I think your version would have been way better, haha. Great work, loved the visuals and gameplay!

Good job, this was a fun one.

One of my favorites so far. The mood was good, art direction, everything really. Really enjoyed it!

Fun and Engaging Game, Gameplay and Mechanics are Amazing. Good Work

amazing management game, fits the theme well.

My god this game is genuinely stressful. The first person view, the submarine interior, and especially the way all the systems worked believably made it incredibly immersive compared to similar games.

I just barely scraped by with terrible air purity and probably 1% of my oxygen tanks left, I really thought I wouldn't make it. Especially so with this damn corner springing a leak every 0.00001 seconds while I repeatedly overcompensated with the ballasts

The only real suggestion I can come up with is finding a way to make the game begin with that pressure and stress, because for the first 30 seconds nothing really happens, and in my first attempt I just missed a few leaks at the back of the sub because I stopped playing to sip my coffee. Perhaps starting the sub in a bad condition but giving the player a short grace period to fix it could work.
