Work in progress, trying to get some finesse, so it's a little rough around the edges on gameplay.
Layout speeds up the longer you play, loops speed you up if you don't jump through them.

I made a comment on arcade but let me re-write it here too. Graphics are nice but there is a -kind of, bug i guess. If you keep pushing "up" you jump over and over without falling down. You may want to check that out.
I like it!
