I really enjoyed this game but yes, things could be added such as:
Hud size increase/decrease - was a little small for me
Colour changer - Something standard that could be added
Maybe customisation on vehicles?
Track editor?
Mid-Air control - Back flips/Front Flips etc
Full quality control - Instead of just forcing low quality
Some slight changed need to be made but i really do like the slow motion feature and the fact there is multiple cameras, so overall im going to give it a 4/5!
Sprinting would be nice if it was added. be awesome if we could unlock more than one attatchment and put more than two on each weapon too. be nice if we could see what the challenges are as we are mid game. otherwise, fantastic game that needs more recognision! 5/5!
