My first try was a 2 off, so I said to myself, oh I know what sneaky thing FlashBack was going for... so I tried another path it was also a 2 off. Mild suffering ensued, but I got there in the end. Great level with lots of fun options. Happy to beat this as the last of the "99th" levels!
21.10.2009: I am the one, who found 2 off (and 10 off and 8 off ...)
Have 50 tries already, and will try more ! Great level! :) Edit: I cannot believe I finally found the last 2 steps! 75 tries. EXCELLENT LEVEL!
