I managed to cobble together enough code, and make a few levels to be able to release an actual game. It's late, so I'll wait to go over the specific's tomorrow. For now, download and extract the .zip (windows only), check the readme.txt, modify the SmashPcCfg.xml to configure your controls if you wish, and go!
Let me know if there are any issues.
EDIT: The previous version didn't have all the .dll's required to play. If it failed to run previously, try this one.
