Well done gameplay! The slime controls were simple yet functional and managed to capture each slime's individual strengths incredibly well. The level design was clearly thought out and enabled players to work around weaknesses in each slime that would've otherwise rendered a puzzle unsolvable, a job well done on the gameplay.
My only complaint is that the cannon sound-effects were rather overwhelming and repetitive when compared to the music. So you might consider turning those down a few notches. Overall an excellently made game.
I want to wish all fellow game developers and artists good luck in the Construct 3 Game Jam!
