That was a fantastic entry for the GBJAM 4 and one of my absolute favorites (and that's why I think it deserved a much higher rating)! While the gameplay is easy to learn, thanks to the puzzle design it gets harder and harder to master in the later stages. The whole pixel art is simply gorgeous and yeah, I can't say anything more, but it's a stunning game. <3 Happily I wrote a short recommendation article about your game on our blog and also uploaded a quick gameplay video of it. :) I'm hoping to see more stuff of you in the future!
Best wishes,
Sebastian
