I never thought I would say that breaking this game was some of the most fun I've had!
Just trying to use the physics to break everything was hilarious to me.
Moving on to more useful feedback lol, the character sprites are adorable! I love em! The fire particle effects are beautiful and I think you hit the nail on the head with them.
My only real complaint is just the movement felt like a constant struggle. Either I'm garbage at your game or not understanding something, but to me it felt like a slog trying to be accurate with the movement.
All in all though a really fun game idea!
Great job chief :D
