Nice graphics and okay background music (only one instrument isn't great). I managed to beat the game and the difficulty curve was alright. Though the three spikes in a row seems to be bugged; hitting the first and last one does three damage. Perhaps you can also better explain to players (through level design) that they have to jump on the middle one to get across. There were also quite a few jumps that the monk can barely make. Lastly, in level 5 the "congrats" text appears at the start of the level, instead of at the end XD.
