A few comments:
In the city levels, the "floor" of the buildings sticks out past the walls, you can bonk your head when trying to jump up if you're too close.
Moving platforms feel wonky to use in my opinion, teleporting you into the center when you stop moving. This teleporting also causes a bug in the city level where the platform goes through a building: as long as you don't move you'll phase right through with the platform.
If you walk up against walls in the city with larger chest sizes, the damsel's boobs will actually move forward off her chest for one frame before snapping back, then moving away again...
There are times when invincibility frames dont seem to work, like when bonking your head off a ceiling when touching an enemy.
