"A lot of the optimizations we did for Will of the Wisps ended up in the Blind Forest version for Switch, so that was a nice side-effect.
Another thing people maybe don't notice immediately is that Ori's sprites were animated at 30fps on Xbox/PC, but for Switch we were actually able to update the animations to 60fps due to all the optimizations, so technically Ori actually even animates a bit smoother on Switch than on the other platforms :)"
