The first of many Braid clones. :p
Overall, a good game. Speed is a little high, might want to slow it down a bit.
Might Also want to add an Application.Quit() onto the escape button, or a pause menu in general. Also found that sometimes I would hit space and just not jump. Also, quick and dirty sounds could be applied as well.

Please Note that you cannot jump from the position below.
Also, not going to lie, I could see Markiplier getting very angry at this game. :p
