the puzzles were a bit easy so i often felt like i was fighting with slow movement, but the color changing idea was super cool to see implemented. however, i feel like the door sprite should've probably been something else if it was hungering for a color to help with clarity for what to do in a room, as sometimes it's a box on a tile which activates the door and sometimes it's a color, so something to visually distinguish between which the player should be focusing on, especially in rooms that throw everything at you would've been helpful. also i noticed the sprites jittering while moving boxes around, i had a similar issue in my game but i was able to fix it. we both used godot so likely the same thing would work. let me know if you'd like any advice on that!
