Really charming little game, I'm curious what it will lead up to!
Just a few minor things;
-The character moves faster diagonally than he does when moving on 1 axis, feels a bit funny.
-I played with a controller, and the game shut down when I pressed start :p
-The pixel scaling was a bit weird for me, it would probably help if I could pick a resolution. I'm guessing you're using unity, I suggest rounding the camera position to the nearest pixel each frame, your art will look so much better that way :)
