Doesn't really work how it should.
I don't think it really works how it should, when I shoot at people they seem pretty much impossible to kill and also the reticule will only be there if i have my mouse pointer actually next to my character.
These are the only two bugs i found within the game as I couldn't carry on playing after i found these because it was too awkward to play (because of the bugs)
Try fixing the bugs and re-submitting and make sure to check the game before submitting!
