Started by going down (a lot). Found myself at a thing that said "Rx5 <--> J(u)MP", so, OK, maybe it's telling me to hit R a lot. Not really, no. So I go right and then hit R...and now it's reset me to be on top of an inverted cross. And I can't go anywhere from there.
I think it may need some more work, if it's possible to get perma-stuck within a minute of starting.
