Thank you for bringing this to my attention in the discord chat. I would have missed it out otherwise. I really liked the unusual scenario for the game. It reminded me a bit of "The Forest", which has similar "cave-diving" levels. Claustrophobic underwater mazes with survival elements is a cool mix and makes for a great creepy athmosphere. :)
I too had problem in the first underwater passage, but reading the comments helped me with the movement controls. I also died on the first stone trap later on. Didn't save until then, haha. Should have made a warning there, had to start from the beginning again. Apart from that it was pretty smooth sailing though. Dungeon gets more creepy the later you are in the game. :D Also lol@ the final trap at the end.
There are also a lot of cool mechanics in the game, like the pushing crates around or destroying barrels, the rock traps, etc. You managed to do a lot of stuff there and it adds some great depth.
I enjoyed it thoroughly. :)
