Great demo, love the frog!
Some small suggestions:
- Would be nice to be able to jump out of a roll.
- Also to cancel attacks with rolls. Bayonetta does this, and Dead Cells as well, but not Dark Souls or other more deliberative combat games. I prefer it, but if you want your game to be slower don't put it in.
- The moving platforms feels a little unanchored, might work to add them to rails or ropes.
- Crouch animation on the main character. It doesn't need to make the character short, just make the character to look down or some other kind of expression (like in SotN Alucard doing his cape move).
Good luck with the development!
