Overclocked is a very short and superficially simple homebrew NES platformer that was developed for the ByteOff! 2020 Game Jam. You control a mouse cursor, and your goal is to get to the floppy disk on the other side of the level. A second player can also control the floppy disk itself and both of you can work together to make contact. However, if you or the second player doesn't move in a certain way the game dictates, both of you will be reset to your starting positions. Sounds frustrating, doesn't it?
LoganTheTASer and nymx both control the mouse cursor and the floppy disk in this run and have them meet repeatedly in record time.
You can get the game here.
Watch this run being played back on a real console.
