Congrats to Muli to finding a major cheese - I didn't realize that the AI behaved differently in Unity vs UJS.
This level IS NOT SOLVABLE in Unity as the AI acts differently and I couldn't route around this.
So DON'T PLAY this level on the Apple app, Andriod app, standalone client, or Unity on your web browser. Unless you want to look for some epic cheese :)
Instead USE UJS (through your web browser). I'm sorry about this! (It also works in Flash, although you maybe shouldn't use that.)
Best of luck!
