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 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.
I'm 2 off and have been so since my 1st try. Great level, for me ! Will try more ! Edit: Wow, it took me 70 tries to find the two ! And now it seems easy, of course ... :)
