Some good, some bad
The retro graphics were charming and well done, I especially like the limited color pallet to give it sort of a dreamy feel. The music was catchy and a joy to listen too.
My main issue is with the rules system. It's used in some clever ways and it is rewarding when you finally pull a level off, but I can't help but feel it's an artificial way of making the game harder in lou of creative enemy and level design. If each level had a different set of rules or the rules could somehow be used to the players advantage, it would be a little more satisfying to play.
Otherwise, I feel like there isn't enough in this game to keep most players coming back.
