Great use of the jam theme and the puzzle pieces were super cute.  I like that each puzzle is short and  joining to get better feels nice. Also I really liked the level select screen and that getting squished by the moving box did not glitch me out. My biggest complaint was having three control schemes. I'd have like to use space for  the jump on red as well as the combined character. Or have w be the jump for both. Maybe even let the arrow keys work when combined.  For me the difficulty of the levels felt out of order. I think three and four were the hardest to pull off and that level 5 was way easy. Also I would have loved to see more puzzles or mechanics that needed you to be together most the jumps could be made by solo characters. Though there might be a bug where the solo characters can do a double jump against the wall if they almost reach the top. Really a solid little puzzle game though Good Luck with the jam and I hope you keep working on it.
