Finished the Lost City and there is for sure some funny stuff going on with collision. I've tried to spin attack a few lizard enemies, I definitely touched them but they stood there unharmed, then Coco ran in the opposite direction... without me touching the D-pad at all. I almost fell into a pit before I frantically pressed buttons to get back in control of her.
There needs to be patches on the horizon.
In Crash 1? The upright lizards are meant to bounce you back when you touch them from the side. I don't think you've ever been able to spin them.
