It's football (soccer) played by footballs. You are the red ball. Use MOUSE. The red ball will move (at a limited speed) towards the mouse cursor (when play is under way). The blue balls are bots, which come in teams of #1 - #7. If you win, the size of the bot team increases (up to max #7). Each match is the first to three goals. Full Screen Recommended. You can play on mobile devices but it's harder to see what's happening.
The original ambition was to make a 3D game inspired by Rocket League but it ended up more like Pong. The footballs are sort of 3D though, and finding a way to create that effect (which requires 90 costumes) was the trickiest bit. The circle-circle collision scripts are based on a helpful website guide - the link is in the main sprite. Postscript: just realised there are a whole bunch of projects called Pocket League already!
