@mobichan: As long as it's only the blade that changes shape it's doable at this point(entirely an issue of scope and remaining budget!) I could even make it change depending on your equipped talisman, so it'd actually be a weapon change.
But I have a feeling that won't be entirely enough for something like hammers - It'll probably look weird handling it the same way that he handles the blade? At least the timing/speed would have to change with heavier start, and recovery after a swing, no? Maybe I could tamper with the animation speed somehow?
A bare minimum idea is that your talisman changes the length and width of the slashes(like short sword vs a claymore).
The snow is currently a simple a physics particle effect without any collision or "fancy" settings turned on. I'm actually unsure how performance heavy it is!
I've played with the idea of somehow rendering it as one active but it'd have to be either tiled perfectly or a really big single object.
Another idea I have is making an actual shader effect that moves tiny pixels around. But I don't know if that would be heavier or faster than just using current effect.
@Volnaiskra: Those are among my references actually! I also check out various 2d fighting games.
I think the issue I'm fighting is that I need to be careful with what particular move that I go with since I do have limited space for moves on the key combinations.
So I need to make sure that the new move adds something that the current moves doesn't. Or figure out some new way to handle a wider set of moves on the fly. One idea on my mind is adding 1 more attack button and use the same key combinations that I do for the current attack button but with different moves. I have a naggin' feeling that It might get confusing though. I also play with the idea of having timed combos (pressing Attack, attack, attack would do something differently than Attack, <pause>, attack, attack. The issue with that though is that you can get your timing thrown off during the slight freezes upon striking enemies.
@zip2kx: Yeah, I've seen his presentation on it a while back! While I haven't played Bayonetta I thought Metal Gear Rising had some neat over-the-top stuff!
