Good stuff.
Great graphics and atmosphere, especially on the sidescrolling levels. the FPS level was a bit of a low point but I did like how you could damage lots of different crap you shot at. (I was actually making a shooter years ago that let you shoot and destroy just about anything you saw... never finished it though :( )
But yeah like I said above, really enjoyed the atmospheric elements in the sidescrolling levels. The rain and lightening and shit like that. Not enough people do that in their games, I always try to put atmospheric elements like snow or clouds or rain or whatever in my games, so it's cool to see someone else with the same mindset. Keep up the good work. It's a shame you couldn't finish this project, but at least it's way more complete than that other half-finished game you made. Personally if you couldn't finish this I would have just quickly wrapped it up and not make it evident that it's an incomplete project. It's a decent-sized flash game, but by telling people it's incomplete it almost makes it seem smaller ya know?
