Propelling yourself it's really hard... I couldn't do it... And I was there almost 10 minutes...

Since I made the level design last and had to do it fast I couldn't make anyone playtest it, I just hoped my hints would be enough to guide players to make the right actions, however just like in your case when I made someone play it yesterday he had trouble figuring out how to build and unleash momentum. Clarity was indeed one of the major problems of this game. Thanks for trying for so long and I'm sorry for the frustration it must have caused :/
