The levels I enjoyed most were the smaller more compact levels. The mazes felt a little too long for the puzzle that needed to be figured out. Was positively suprised by the introduction of the crystal slime, but thought it could have been integrated into the already established game loop a bit better (almost felt like 2 different games when the puzzles shifted from block puzzles to matching the colours. Maybe in a full release the crystal slime could act as a switch to unlock doors? Overall enjoyable game with a lot of potential. Check out our game, we went with a similar but opposite mechanics where the slime trail provides area you can move across freely :)
