Interesting concept, having the room fill with water the more you die. Was there a specific reason why I was a balloon. To me it didn't make much sense as balloons float.
The game definitely needs quite a bit of polish though. I got to the level with the jug and had no idea what I the jug did. I couldn't seem to get up to the first platform, and for some reason, the cactus kept disappearing.
My main suggestion would be to make it more clear to players as to how to play, at least until the main mechanics are understood
