Your game was a lot of fun! I enjoyed the puzzles, and found myself wanting more difficult complex ones as well. I especially enjoyed the levels where you had to rush to get your rock before the pushing slimes knocked it off the platform
Glad you like my game,, also yeah you are right pusher slimes are created to annoy the player, I remember my brother saying those levels were unfair when he was playtested, but when you get the hang of movement it isn't a hassle
