Great retro-style game!
The art-style is really beautiful. Music is very NES-like and soothing. Gameplay is nice and simple.
The controls seem to be a bit rigid, but that goes away after a while.
Art-style & graphics: 5/5
Gameplay: 5/5
Music: 5/5
Overall: 5/5
A very nice game by the author. Keep up the good work!
