Nobody was online when I tried, so I queued up with myself. It worked pretty well! I don't know if you're familiar with Ibb & Obb, but the two-person co-op puzzles in this reminded me of that. The art was simple, but very good. The puzzles were pretty easy (probably because communication is the real challenge), but there was a good difficulty curve and the final challenge was a good brain-teaser, The audio assets you used were implemented perfectly so it fell like a professional game in that department. Great job! I'm super impressed you implemented multiplayer for a jam game.
