I wish there was a reply function on here, but I'm wondering how in the year 2018 you still have game speed tied to CPU speed. I thought that was a problem we grew out of after the 90s?
Toodee is very slippery to control, he's heavy and has way too much momentum, but in levels where you have Topdee push crates to create platforms I find that jumping and them moving a crate so that Toodee lands immediately when switching helps immensely.
One more note, those business that are "useless"? They upgrade other business when you reach certain thresholds... although set thresholds are ridiculous.
