This is such an amazing demo! Definitely looking forward to full release!
The only things i can say i would change: better gore, it would suit the nature of the game so much (i hope i don't sound like a fucking psycho, lmao) and a way to reset the test without resetting the game, something like CoD4: MW combat test at the start of the game, it would make the process of having fun with the demo much easier! Good luck with this project, so far everything looks amazing for this game!
