Nice job! Realy nice art and good sounds, but the gameplay has some issues. First I think character is too slow, it just makes game boring quite soon, second is that when air runs out, the game instantly resets, adding a simple slow blackout before resetting will give player some extra time and give the fealing of a last second which makes game more fun or smth (will give more emotions overall) and the player is too far away, it makes game a little uncomfortable to play, since you alredy have camera movement you could just zoom in a little bit.
And some bugs: I`m not sure if it`s a bug, but I could only buy 1 Item, And, the most important, maze entrance is too small, character simply doesn`t fit (or there is some other reason why I couldn`t enter it) which makes game incompletable.
But overall It`s a really nice meditative game, Good job! especially for only about 2 days.
