Thrilled you like it!
A lot of things are planned to change, actually- i know camera controls are not optimal, i experimented a bit to see if i can get something that shows her face more because the character looks boring af from 3rd person view. That's going to change too, since she will have a cape as soon as i figure out how to implement cloth simulation :) Point is, now i'm aiming for a camera like in hellblade, going all around via look controls if you're still, following along from behind if you're moving.
Onto the combat system, i'm planning timed combos, and a physically accurate shopping bag to do the smacking. Different bags with different things in them work differently (you can put a brick in there for heavy attacks, but it kills the stamina along with the enemies).
I'm planning a menu system that goes on in her apartment, so Esc key will naturally have to be a thing, along with in-game instructions.
The biggest change for next version will be how the game plays out. It's not going to be a wave shooter anymore, but a tactical use of limited non-regenerable stamina to reach a certain goal. Else, she goes hypoglycemic and faints, you have to start over again. You can use this limited stamina to sneak, run or fight, the point being to reach a certain point in space, like the store or the pharmacy.
We'll see how that goes.
