That is the loveliest most thorough review we've had! Thank you!
My boyfriend had intended to make the art assets all graphic, but he got frustrated so reverted back to pixel because he knew he could churn out something decent in the 2 hours we had left at the end of the jam.
Music-wise, I had intended to make a b section and more melodic variety generally, but again ran out of time. The piece is all loops that stack in and out, except for one steel drum/marimba part that I improvised over the top. For a polished game I'd defo bring in muuuuch more variety to the piece, and also probably have the music whilst you do puzzles be less intrusive and more sparse.
