*Splat* *Plorp* *Squet* *Pfft*
You're a piece of goop stuck in a loop.  All you can do is jump and stick to make the loop roll using physics.  You can aim your jump and have some air control, so it's a matter of being patient and clever in order to build up enough momentum to get over hills and other obstacles.
Roll the loop up hills, over gaps, and other obstacles.
Be encouraged/entertained/enraged by my narration as you attempt to reach the top.
Fall back down and lose a bunch of progress, probably.
Question your life choices.
