Feels like a mix of Club Penguin's Pizzatron 3000 and SM64DS/NSMB's Sort or 'Splode. Unfortunately the instructions got clipped off the side of my screen, and the difficulty takes multiple minutes to get into a "Out of Control" state and is quite boring before that point. Mixed pixel scales also aren't that appealing, and there's no audio to speak of. No quit button either, had to use Alt+F4 which is a keyboard shortcut that some people aren't going to know.
