Fun with some buts. I liked shooting mechanics a lot. Driving forward is also totally ok. However steering leads to full stop and makes me sick, just like jumping on hills that I tried only once because of that. I tried not to turn much. May be it's just me because I haven't played VR car or flight simulators and have nothing to compare steering with.
It would be also great to make target destinations more clear. Monotoneous background gives no clue where to go. Luckily the level is not large.
Also I would not expect the game to quit totally when I loose or win. Returning to the main menu seems more acceptable for that.
Overall good start and can be improved. Shooting mechs from the car is really fun.
