Nice. It worked quite fine for me, with basic on-board Realtek AC'97 audio, though I think the sounds in general will need a bit more polish to them. I found the footstep sounds to be a bit distracting (maybe too loud or distinct), and a couple of them sounded noisy/distorted at the end of the sound.
I really liked the graphic design of this. I think it looks great. I'm envious of that talent.
I haven't gotten past a certain enemy with an affinity for percussion, but I think the player character will either need more martial arts ability, or weapons, if they are not already there. I envision this guy with a gun of some sort.
Speaking of that enemy, I guess I'm getting too slow in my middle-age to dodge very well, or the things that need to be dodged could be a tad slower.
Very nice demo. I hope the project proceeds well for you. Now to see if I can get farther...
