I beat the first level and closed the game not knowing that the game kept going >.> I don't feel like doing it again so I'll leave my impressions up until that point:
+ At first, the game graphics scared me off in a bad way but you actually managed to mix all simplistic resources (sprites, words, music...) into a very unique style that works somehow. The lyrics was a nice little touch and fun :P
- The controls and direction are not very intuitive. This could be improved but I had no trouble beating the first level after I got the hang of it. It certainly entertained me for the short while I played.
+/- The level design works as it is. But there are certain things that bothered me like having low visibility. I didn't know where I was going at some moments! It'd be nice to zoom out everything and make the map loop.
Rate: I give it 2/5 because while it has personality to it, it needs more polishing (mainly on the controls).
Good luck!
