The Eternal Ragequit

This is a troll map with 10 levels - 11 if you count the lobby. (Hint hint!)
I would say Level 1 is the hardest but see for yourself - maybe I only decided Level 1 was the hardest because this map is from three years ago and I had to untangle everything a bit and L1 was the hardest to untangle.

Despite what you probably think, the "Get Trophy" button at the end is not a troll.

A few notes for those of you who plan to take the map apart and figure out how it works:
1. The commands used in this map are fairly complex. You might not understand them.
2. By the time you finish the map, the commands will not be what they were before. If you want to play the map and then read the commands, the map will not entirely work. You may want two separate copies if you want to do so.
And 3. Several of the command blocks' output refer to a player "KaLPoi". This is not a glitch, it was my old username before I found out and changed it.

I hope you don't ragequit Minecraft!
