It's YOUR game after all, and my opinion represent only my point of view after 20mins of gameplay so yeah take my comment as it is :D
Having the opportunity to try different fighting style is something I except from this type of game (but It's a lot of work to add so I don't mention it on unfinished project), that something I would love to try.
Yeah feedbacks, I don't know why I forgot this word :D
I'm pretty curious so let me ask you few things:
-Do you plane on making this game a product or only an amateur project?
-Is it your first game?
-How skilled are you on code? I mean do you know various languages, have you done years of work in a company, stuff like that?
-I would like to try Unity(2D), but for the moment I only got some basic knowledge in C (from my school) and doing some stuff with game maker. Do you think it's enough to start a project on unity, at least if I do their tutorials(ya know, the roll a ball, 2D ufo, 2D roguelike, procedural cave generation) or it's not good yet and I should have more experience on OOP first, or even in C#?
