Interesting stuff. I, for one, quite like the art direction. THe enemy designs are pretty good, and the lighting looks really beautiful.
I'm not entirely sold on the gameplay, though - it seems like at present, there is little challenge other than being a really good shot. Not much strategy, or interesting terrain/ai to take advantage of. That judgement could quite obviously be premature, though.
The game is inherently simple, all you do is shoot and dodge shots/run away from enemies. However, we're making that simple concept as deep and interesting as possible.
We're adding more enemy types every week or so, and they really help make the combat more interesting. When we added the guy that hops around and explodes, it dramatically changed the way I play. I had to not only circle strafe around shooting enemies, now I had to make sure I kept my distance from the hopper as well. I was actually considering starting health in half before we added that enemy, now I'm not so sure.
So, once we've got more enemy types, the game will be a bit more interesting.
Also, the rooms in the video are far from final. They're just test rooms. I'm more focused on implementing and balancing weapons, items, and enemies right now. I'm not dedicating much time to level design yet.
