Wow this game is incredibly pretty, excellent job with the visuals. The ending is so lovely as well! I could imagine a full game like this with a similar mood to Yoshi Woolly World. You and chicki, climbing levels to get to the beautiful sunset.
The gameplay is simplistic but fulfills the limitation, and platforming feels good. I think more variation with the powerups would be good but this is a very nice start.
Good job!
