I wasn’t quite able to finish this (I got stuck on a level with a pawn and four green buttons in each corner), but I enjoyed what I played overall! It was fun to try and come up with a plan just based on the numbers at the start of a level, though that started to become more difficult as the levels became longer and the paths through them less obvious.
My main criticism doesn’t actually have anything to do with the puzzles, which I think were generally solid, but rather with the movement: you move quite slowly, which made longer levels frustrating to attempt, and turns can take an inconsistent amount of time to finish, so I often found myself accidentally walking off the edge of the map. That frustration distracted me from the puzzles I was otherwise enjoying. If the movement was sped up, and the player was prevented from leaving the map, I think the game would be a lot smoother to play. Otherwise, though, I had a good time with this :)
