Very fun! I really like the concept and the light nature of the art and music. Really simple controls, if you had scroll when the mouse is near the edge of the screen then you could play it entirely with the mouse. Nice job!
Glad you liked it and thanks for the feedback. The only reason it's with the arrow keys actually is because I wanted to do it fast and reliable (so, keyboard at the time being) and change that later. Turned out, that later = never :D
