I have to say your game is really awesome, I like it!!!!!
Keep going and this will be an excellent TPS game!!!!!
But I would like to suggest that you may add a scope effect to weapons like sniper rifles, which will make them more comfortable to use.
BTW, the role acts wrong when I go upstairs, she just don't move. So I have to press 'space' to jump up, that is quite inconvenient, maybe you can fix that ; )
Anyway, I really enjoyed your game. Its performance, music and shooting feel are all great. I can't wait to play a further version, and I will be waiting for your good news ; )
(I'm from China, and my English is not quite good, hope I made my words clear, thanks for making this excellent game)
