Just a basic runner game, Arrow keys to move, up arrow to jump, down arrow to smash, light grey is bad, dark grey is ok, black is conveyor, coins give you three points! (W and S control music volume, ninja power-up gives you faster speed and higher jumps for 10 seconds, mega coin gives you 25 score and makes regular coins worth 10 instead of 3 for 15 seconds) post your score in the comments!
I got inspiration for this game from the many runners ive seen on scratch!
