I want you to know that I haven't this excited for a fan made project in a long time. You're off to a fantastic start with this, and I was very impressed with the demo.
Only big things I noticed were slight things during battle:
There was no window to escape the canodumb's attack once their sights reached you- it was automatic.
The buster's shots don't fire quicker when you're closer to an enemy as they should.
Also, the swords are a bit too quick.
Otherwise, this is so great. Keep up the hard work!
