Hah Second high score :3. A must have which I am surprised there is a lack of is the reload feature just by pressing Spacebar or R. Feels like a hassle reaching over to the icon, unless the challenge was what you were aiming for. The game also lacks depth, I'm not saying there's anything wrong with it in its current state, for what it does it does it well, seems polished and professional. However reaching for a high score is not really a gameplay mechanic that works nowadays. Try adding achievements, added levels with different backdrops and music, different enemy types, or perhaps even a weapon upgrade system although personally I dislike those. Good luck with the game!
Just not... addictive enough...
Good job with the shaders, it's impressive but a bit too bogged up, too much clutter and hard to see anything. Otherwise it's just a majorly toned down Counter-Strike, there's no incentive to keep on playing, try focusing on gameplay instead of graphics.
Thanks! :D
