A set of 5 small Pico-8 arcade style high score games featuring brightly colored pixel graphics. Each game operates on a different mechanic. When initially downloaded, each game except the first is zipped separately with a password, and you need to earn a B rank in a game to get the subsequent game's password (or, if you give up, you can just check the read me file to cheat the system). I thought that was a pretty creative way to encourage players to give each game a try.  The hypnotic rainbow-static visuals are also quite unique.
