Very cute and fun to play game! I really liked the art and sound design. I found out the hard way that the pause menu does not stop the time completly :P
One bug I found is that in level 4 or 5 where enemies spawn from the top-right corner I managed to leave the playing area there and come back from the top in the middle where there are no platforms to stand on. Then I left the screen and couldn't find my way back :C
