super cool! love how transferring expansion became really core to how the puzzles were designed, kinda paralleled how I ended up designing scaling blocks in my game too. I think a more intuitive control scheme could be nice. I also love how you can realize the transferring expansion works in the early levels, but it might be nice to add an extra puzzle at the start that forces the player to learn how transferring expansion works as an isolated mechanic before the first level that also introduces the shrinking limits!! overall love it
