Really liked the game. Pretty hard to get on the leaderboard I guess?
2 things. I noticed you can see through the walls when you are in the vents, you could disable that option.
And I don't know if it's ententional, but at the end when the water is almost all the way up, there is a part where there is no water. Maybe this is done to have a safe spot at the end, but perhaps it would be better to have a door there, so there is a reason the water doesn't get there.
