Hello! I am new to this site (but not to RM).
I played the demo, and first off, I want to say it is obvious that you guys have put a lot of effort into this project. The maps are good and the music is great. Animations are way good, and the abilities are fun. I really like the power-up move for the "blaster" weapon. All in all seems to be a solid, well programmed, very clean looking game.
As far as critical feedback goes, there are a couple issues that I feel could be better and would make the game really shine. Grammar is one of them, just like others have said. But I think the weakest link is the story; specifically, how the story is presented. For example, from the player perspective, I have no idea why Razh and Millia are together on a mountain at the beginning of the game. I'm sure you know their back-story and all that, but to me it doesn't make sense why Millia cares about Razh, why she keeps flirting with him, or really why they are together at all. Why does she need a bodyguard? Why does he care? Can you see why I would feel that way? And there is really nothing in the initial story "hooks" me. Millia drives the plot because she is looking for a special gem, but based on how ditsy and flirty she is, she isn't really a strong character for the job.
Have you guys written out the dialogue in word format or with a text program? (i.e. MsWord or FinalDraft) It would be helpful to get someone on your team to do some script editing (text-script, not programming script).
But overall I have to say it is a very solid WIP. I only offer such detailed feedback because I can tell you guys have worked hard and want to make the game as good as it can be. We are all amateurs after all, and I respect all the effort you have clearly put into this. Keep up the good work!
