O.O interesting, yes. Storyline: pretty good! But-
I'd give you a ten, hands down, except for that glitch where you can't switch back.
The way around this, is to get autofire weaponry ^_^
...and to get autofire upgrades for anything that can... yeah.
Just don't switch your weapon (there goes that 10 dimension D: ) and you're fine.
...so close... soooo close...
Btw, about that thing, the ideas part... uh...
0.0 Have you considered splicing several of those options, if applicable?
Also: Define RPG... you don't even wanna know the things I've found under that category these days xD It lost it's original (and honest) meaning about a year or two ago D:
^_^ Just a thought.
