Runnerman

Simple endless 3d runner. Use A and D keys to move left and right respectively. Spacebar to jump.
item breakdown:
Coins = score increase, Flags= 10 seconds off timer, diamonds = jump increase higher and farther
Objective: survive until the timer reaches 0. This will progress to the next level. 

leveling up = higher obstacles and collectible spawn rates. Time increases as well.

If you collected >= the amount of coins for the random level requirement (anywhere between 10 and 50), you will get 10 seconds deducted at start of next level!

You can take 2 hits, third hit = game over!
