1. Thanks for playing! :D
2. This is really good feedback, so thanks for taking the time to tell me about your experience here.
I think you're right about the inputs. While the combo inputs are meant to be skill based, they're probably a bit too punishing as is. This game is very much inspired by DBZ: Legendary Super Warriors and its combat, which is where this input system comes from. Despite that game's fans liking them, I know they're not for everyone and I do intend on doing something to further improve that experience.
Regenerating health to make it feel more like a fighting game isn't an out there suggestion at all. In fact, the ARCADE mode (not in this demo) actually restores health fully between battles like in a normal fighter and doesn't contain any roguelite elements. Perhaps I can experiment with smaller pools and/or partially restoring health after combat during the roguelite mode though :)
What you mentioned about the music -- you're right, that just flat out sucks, I'll fix that ASAP.
Again, thank you so much for playing and for leaving such great feedback for me!
