First Try!

you use the right and left arrows keys to move

space to jump

tab to time travel

r to reset the level

in this game you are a time traveling block. you are trying to reach a flag towards the top of the screen but you cannot jump high enough to reach it and there is nothing to jump off of, furthermore You must complete the objective before time traveling! future versions of you are allowed to help you, but the one who grabs the flag can not have traveled through time.  (simply put you must help the first version of yourself reach the flag)
