Hi,
just downloaded the demo and tried it. It's definitely a lot of fun. I like the crazyness of the action and the dual wielding of the weapons a lot.
One thing I noticed was that when jumping the animation stops before the character is on the ground meaning the last bit of the jump looks weird. Also, picking up weapons didn't always seem to work.
Other than that I had great fun blasting the enemies, especially when I got the uzi and the rocketlauncher^^
Keep up the good work!
