You coud've at leas add your models and textures,not just copy youtube tutorial.
Also,there is some things that also caught my eye,in bad sense:
You gain score by strafing cube only.
When entering your name,it shoul be possible touse keyboard,and why tf isnt it in normal keyboard format.
Falling off the edge feels very cheap.
Still,UI looks amazing and with some theme (biker running throught people would be fitting),game would be quite fun.
