Apart from the resolution problem (Wasn't working until I zoomed in as was already mentioned), the game gets quite repetitive fast.
Also, I've discovered a bug where if you press mouse 2 you can just stop running which makes the game a lot easier since you don't run towards the enemies.<p>Also, was it intended to run out of ammo after the 5 minutes?<p>And sometimes the zombies would bug out and go through cars and etc., weapons have short range so the player can see when they disappear in mid-air (maybe that was intended) and sometimes zombies stop coming after you unless you go in their direction.<p>Aside from that, the game was fun to play for the 5 minutes, to kill some boredom.<p>Screen Resolution: 1920x1080<p>Browser: Firefox 73.0.1<p>Linux Distribution: Arch Linux
