That was exactly intended. However, it was supposed to kill you and that would have loaded the actual game. That part was missing because of miscommunications. We had the concept that missing that double jump would wake you up in some sort of purgatory where you would have to work your way to heaven (or hell) based on your choices. 

We are proud that we got something posted, but it always sucks when your idea doesn't come to fruition.

Thank you! See the response I gave above you. We meant to make the double jump impossible. Just never got around to getting the game to work the way we actually intended. That was supposed to get you to the actual start of the game. ;)

Thank you so much! We did our best but never got to do what we set out to do. I may well try to get my idea to life now that the jam is over.

I read the comment wrong at first. It is fixed now.
