I like the setting of the game and the first person perspective. Game me Subnautica vibes when I took my first dive :)
At first I wasn't sure what I was meant to do, but I think you swim underwater to fix the broken pipes? There's a button prompt for pressing F+J and that might be to speed up the repair process, but I'm not sure.
It was also a bit confusing why there are two resource meters. I understand that the blue is for oxygen, but I had no idea what yellow meant.
There's a lot of interesting components to the game and I would be interested in seeing what the team can come up with given more development time. Nice work!
