Up arrow, space, W or mouse to jump. Hard mode(must be unlocked)makes the game harder but gains you more points. The "Fast" item at the shop makes you run faster which can be useful, each shop item changes the game to be harder in one way, but easier in another, so let's say you don't like jumping, then I would recommend the "Fast item because it makes you run fast allowing you to jump over more spikes at a time. If you don't like running then get the "Big Jump" item, and, if you want a challenge, buy the "Hard Mode" item!
Anyway, I also made it so when you hit a spike you lose 100 pts. instead of losing all of your points and restarting. Why did I want to make an endless running game you ask? well...................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................idk
