I could't even figure what to do, when it came out. Now I reached the exit, but can't find the last two steps for 337. Will keep looking.
EDIT (20 hours later): Got it! The sad part is, I'm not sure, what I did different. Huh!
I disagree with manti but I think it's because of the difference in skill. I found just getting to the exit to be super satisfying and now I'm slowly working my way down from 376
Never find these all that fun but the 2 off is good. These always feel like a three step process.
1. Frustrating because getting to the exit is impossible
2. get to the exit and be never more then 2-4 off
3. take forever to find the last 2.
