The game isn't really the main reason for this post, it's the graphical thing I did with it.
(Although, in case you're wondering, the game is Slime, and it may have a few glitch fixes)
It pretty much speaks for itself. I really only chose Slime because I thought it best suited this game more than any of my other work-in-progress games. Feel free to extract the GART function and use it in your stuff! The function is at the very bottom of the code, and only uses the BAR and BARSIZE variables. It doesn't actually need that line where it references 'SLIMES', so just delete that and you can probably just paste it right into any of your projects. (Just remember to put GART() after you render!)
