This game looks cool in concept, but there's some terrible mouse accel when I played it, also felt there were a little too many enemies, as well they have that Far Cry 1 bot mentality and will notice you from a mile away.
Hi. You played it on Linux maybe? Some friends who testing on linux, before I published it, was notified me the same problem with the mouse, the acceleration. In Windows, at least (I only can testing on Windows) I haven't noticed any acceleration (in my PC and other PCs with Windows where I tested it). The game internally only multiply the mouse axis value with the mouse sensitivity value set in the Settings menu, but not apply any kind of acceleration.
