sry to revamp such an old thread but do you have any plans to continue this work?
From my begginner perspective this is very helpfull, i'm not dying in rivet stage anymore and even just rolling boards i use grouping and 4th/5th girder strategy to pass the barrel boards safe.
Right now i'm having problems in pie factory when the fire down the ladder and i cannot do the free pass. Sometimes i wait too much and have to risk my life because of the timer dying anyway. I'm losing lifes in springs too but i know what to do reading the basic manual you guys wrote, it's matter of time to master this.
Pie factory is the real problem.
ps. as some of you know, english is not my native language, so if i say something wrong feel free to correct me, please. thanks.
