Videogame Sidescroller: Final Result, BGs and Concept Art

It's not programmed to do anything else, but still... HE RUNS! And there's cool music from Sonic and Knuckles!! You can view the process from my run cycle in this entry

If I ever expanded this into a playable game, (
which is a possibility in the very far away future) it would be about a kid named Jethro fighting enemy cyborgs to... do something super noble and heroic!
