there is little to no gameplay LOL. it's nearly impossible to really lose since there's only 1 car for every few seconds. the amount of cars and overall speed of the movement should both gradually increase.
the gas is also barely something to worry about, since it depletes very slowly. just like what i've previously mentioned, maybe the gas can also gradually deplete over time? or maybe just make the gas cans more scarce over time or something (also aren't drones usually electrical? why would they need gas LOL)
and lastly, the highscore rewards are way too high, though this is due to how the score itself rises fairly slow. maybe it can also increase gradually as the speed of the traveling increases? combined with the lackluster gameplay, i don't think it would really entice much players to reach for higher scores lol
i *will* say though that despite the lengthy criticism i've given, i can see that there *is* a game here. i just think with the issues i've listed fixed, it can actually be pretty decent :] keep up the honest work, raphael!
