From the little bit I've played, I really liked the game, but I can't say much because I can't play it.
For some strange reason, every time I lose or win a level, the retry and next buttons doesn't work. I have to restart the page to play again.
It would be great if you could fix this problem so I can enjoy this game. (But it doesn't matter if you don't fix it; I understand that fixing bugs or making games is difficult.)
Problem aside, I love the music for the first levels; it sounds very epic and adventurous. The songs here are also great.
