Your goal is to get from your starting string, 'MI', to the string 'MU' using 4 simple rules. WORKING ON RULES 3 AND 4 DON'T PANIC If you like to spam the 2nd rule, use turbo mode, as it will slow down exponentially as you press. Rule 1 is fine. :P
Based on the MU-Puzzle in Gödel, Escher, Bach. TODO: Implement rules 3 and 4, make instructions more complete, secret stuffs. :P
