A very good game, the UI is very well made and the music is super cool. However, I noticed some problems:
1) The game was harder to understand at first, and the red arrow pointing up gave me the impression that I had to shoot up after the monsters-eyes, not that I had to use the bazooka to jump.
2) The difficulty is a bit high, considering that when you jump you can't see where the monsters-eyes are positioned andbecouse of that I didn't managed to do more than 4 consecutive jumps.
3) Sometimes the game crashes. That is, after you play a round and lose it in the next row, there is a possibility that those monster-eyes will not appear at all and you will not be able to advance in the game (also, the music will not be heard at all).
4) To prevent the possible errors previously mentioned in 3), a pause menu where you can restart or exit the game, would be good.
But the game is great. Good job ! :)
