drafting is meant to be slip streaming also drifting would be nice for a few extra boost as for trying to T-bone a car dosen't work instead it flings the enemy forward giving them the advantage over you this should be change to if executed properly then the enemy car automatically swerves out of control as for the turns it makes it hard to hit things correctly.
to save you need to press esc then quit to title then you can go back to the level and have 5 secs of no lag...but that dosen't help at the the 5 secs of no lag :(
when you get a temple the more powerful towers that are sacrificed the more powerful the temple will be so if you get 21 sun gods and upgrade 1 of them them the 20 rest of them will be sacrificed to make the temple as if its 20 sun gods put into one!
I am working on it :)
