My only real gripe about this is the dash was a bit too sensitive. I think a few times I preformed a dash while just adjusting my position on the keys. I think it was great that you lost your health on death it gave you incentive to not die, anyone who cries about it, is doing just that. As full health can easily be achieved again in a single combo depending on the level, as a few levels I was able to get through without touching the ground and came out of it with four more lives than I went it.
All in all I had a lot of fun playing it.
