Cool! I liked you city background a lot. The physics and coding also seemed really solid. It was fun and challenging combining the elements. A platformer that makes you think??? haha
A couple random things I noticed: when the level after the tutorial loaded, the camera flickered to black and back on a couple times. I could jump and stand on enemies, not sure if this was intentional. I was confused by the tutorial somewhat. It made it seem like my attacks were going to be projectiles, but then when the actual level started, it was all melee. Anyways, good stuff, I hope you keep developing this.
