I like it when a level can be solved in sections; keeps the amount of thinking possibilities and looking ahead within the limited capacity of my brain.
I'm a bit with @Hem. There is no trick to find here (where Ernie still had a possible 2 off) and the only "challenge" is finding the correct exit.
But imho there are at least 4 exits of interest at first glance which could confuse a beginner and have them go for the wrong one at first.
Very sweet, but not so short for me. Needed about 20 attempts before I was even able to reach the exit (and then be 2off).
Solver's satisfaction is high!
