Nice simple little platformer!
Really liked the character design and overall graphics, it does have a solid gameboy vibe for me.
I had a hard time figuring the controls on keyboard, especially start and interact, as I didn't see any instructions in game or on the page but maybe I missed them.
Too bad for the sound as it could have overhauled the experience in my opinion, even simple ones for the jump and picking up the puzzle pieces.
Still all in all a solid game! Congratz!
