Fun concept and nice visuals!
You should look for a rag-doll plugin, I believe I saw some going around on the forums somewhere.
Personally I find it inconvenient how the character goes out of the screen up top and stays out of reach for quite some time, leaving me waiting indefinitely. I also feel like pushing the character horizontally should feel more responsive, it's a bit sluggish.
Thanks for the feedback, all great points! I didn't even think about the ragdoll but now that you mention that it could be really fun thing to add. I will take a look and see if I can find something!
I might look into having the camera follow the character past the top of the screen, it would need some tweaking but it's doable. I agree about the character push, need to lessen the amount of dampening right now to give the player more freedom in the combo.
