Arrow keys to move. It does not end. How long until you break? The forever stairs. Exactly 100 blocks, (I think) No obstacles apart from your brain. If you leave you are only cheating yourself. (In the loading screen, if the top right score freezes, press the green flag again.)
Thanks to #Snartle2489 for the running animation, which I think he got from a tutorial. This is for the contest for 100 blocks. https://scratch.mit.edu/studios/31208332/
