This is one of my favorite puzzle games I've seen in any jam, let alone one that's only 4 days long. This game is extremely polished. You've got excellent art, snappy sounds, appropriate screen shake. One of the solutions had me dropping a piece and letting gravity solve it and the sound effect for a piece dropping into place was so satisfying I had to keep replaying it. The preview and being able to slide to different turns of your solution is really incredible and got rid of any tedium in trying new solutions. Puzzle games are really hard to do on a jam timeline because tuning the difficulty is really tough, but you did it while making a super polished game.
My only piece of criticism is I don't think it's obvious enough that you can move the arms multiple blocks per turn. Once I realized that the game was much easier, but I spent quite a bit of time moving only one block per turn and it took me all ten turns to beat the first puzzle. The second puzzle seemed impossible until I figured it out.
Amazing job I can't wait to see more from you!
