This is seriously great. I really enjoyed the writing. Great dark humor, delightfully unsettling, and the perfect amount of mystery. The exploration was fun. It was a little too easy to get lost, but maybe that's the intended experience. 

Loved it, overall. I can't wait to check out whatever stuff you're going to add to it.

Nice game! The art and the idea are really cool, I hope you continue to polish this game!

Nice little narrative adventure. I would've liked a bit more indication on which direction to go but then again it caused me to get lost which fits the theme lol. Anyway, nice job!

The pause menu was incredible. Loved that. Overall, great game - had a good narrative and the way she talked about her dead colleagues came of as a type of dry humour that I really appreciated.

Okay. That ending was dark. And unexpected oO

Mechanics worked pretty well. Liked the way how you implemented the control explanation into kates monologue. Really nice. And the mini menu with the battery- and oxygen meter. Really like it. 

I liked the atmosphere and the pixel art, but the lighting was a bit too sparse, I had absolutely no idea where I was going.

RIP Richard, I like the erie feeling. Might be good to add some ways of closing off old areas to prevent players from getting turned around and backtracking too far

Good atmosphere, nice pixel art and animation. Good work.

The concept and controls are really nice, it also depicts quite well the darkness and claustrophobic feeling of underwater caves. I really enjoyed it. I also love the menu visual where you can see the oxygen and battery, that looks awesome.

The only thing I didn't like is the crackling of the sound. I don't think that was intentional, but if it was, personally I find it quite unpleasant, Also I am unsure how is the limitation of Time is a resourse done here as it feels like the oxygen and battery are more of a resourse than the time itself, but you are technically still "racing" against the time so not sure.

Otherwise good job.
