Very cute game, tho it is a bit too slow imo (the animation of the frog eating takes a while, also the movement is a bit too slow to be able to fully traverse the level while still having enough oxigen). The graphics were pretty nice, reminds of old games, very fascinating, and the sound design is nicely themed accordingly. I didn't like the movement with [space] at first, but when you get the hang of it, it is very innovative, actually.
