The twist in mine is that I'm actually twisting a classic anime and instead injecting that into a classic game, Uridium 2. Not much of a twist admittedly, but I might have worked out a proper twist by then. Thought it would be fun though and take one classic and mash it with another classic.
I'm solo-ing the game outside of music and possibly SFX (could end up not being the case since he's busy a bit through this week), which will be by Mairu.
