this is actually the most goated comment ever im so glad it reminded you of zachtronics games, im a huge fan of them especially opus magnum! im super glad you enjoyed it!
these are also both two very valid points, a smoother difficulty curve and better animations would for sure be the first thing to work on post-jam! (btw yea having a swap block left would mean you havent beaten the level yet, since everything has to be zeros 😅)
