Interesting thought. though its annoying when i shoot my mouse and don't really know where my mouse will reappear. so sometimes its on top of many enemies and i die :(
if you just down at a high speed you fall through the floors. Also one time i jumped down onto an enemy at a high speed, and when i spawned i fell through the floor instantly. Although it was nice since it was kind of a shortcut.
Wow the bonuses are really well hidden. Once i find it it still takes me a while to understand how its even possible to get... Then i have to do it. Great game
