I agree with what has been said already too. Only one little section is a puzzle to be solved. The whole rest of the route is forced. It's a too big and messy board for just one interesting section. Maybe resizing it could be a thing?
I like those PP1 type levels a lot, but that one is by far too long to keep the fun until the end. At the top of it, if like me you land 2 off, the idea to restart all over hurts... LOL
I agree with Manti's review; tough level to rate. The 2-off is very tricky to activate even though it becomes pretty clear where it is because so much of the rest of the level is filler. Ultimately, I enjoyed solving the level in spite of its design.
