That level with the crazy moths flying up and down!!!???!!! I didn't have a chance!
Fun little game. Love that you put effort into writing different "death-screens". Crazy hard at times ;) ;)
For constructive critisism I would mention that it bugged on me on some levels where touching the portal didn't take me to the next level. Also some kind of sound would have been nice.
Other than that, good job!
*Edit: Oh, and also. best way to defeat a boss!!
