I got major lag on the 9th lvl in the underground part and anytime i got close to the boss on lvl 10 i laged as well. I set the quality to low and still got lag.
Great game but really need the have the ability to change the quality. Also the Coins, Gems, and Fuel Can need to be more transparent. If you get enough of them together they can block out a whole set of spikes. I would of been able to get farther in survival but the lag was insane after destroying 1, 2, or 3 bosses at one time. 9.5/10
