The achievements you put in the game are just not sane anymore. "Start the game"?!?
This game looks more like 'Achievement Unlocked' than a shooter.
Try being more realistic with achievements next time. No one wants an achievement for starting a game. (Or muting the sound, for that matter.)
Still a good game though, could use some instructions for the hotkeys IN the game, for those that do not bother reading the author's note.
