Also I found a fun little bug in polymaniacs after a few hours of playing. If you are using a tank on keys 2 after the game over thingy starts to come in you can press self destruct over and over an you will fly in the air like a helicopter. sorry I couldn't post a video but it is really funny seeing a tank fly in a game.
Which mini-game? I knew this happened in Timetrial as you're indestructable there. This is all fixed now though - you can't shoot or self-destruct when the game is over and in timetrial it resets you to the start position.
