I love this idea, reminds me a lot of Baba Is You. The graphics are clean and fit the vibe and the game is really polished :) As a composer I think it would be really satisfying if after the level is complete a few additional instruments come up to make a short looping light piece of music, the dings that the puzzle element make are so pleasant they’re just calling out to be used in a track!
Well done, I’d love to play a full game of this!
