this was a very cool demo i liked that running over the guys sent them flying and the bigger guns were very cool, I have not played any tank games before so I don't know if this is meant to be more realistic or cartoony but it seems pretty good so far.
I don't think the frame rate was automatically capped so my pc spun up a bit. also the edges of ramps were a little sticky i feel like the tank should definitely go over small bumps like that
