According to the Twitter feed...
The Steam patch was a few small fixes and the addition of ULTRALOW detail setting for people who have really shitty pcs :)
brb, putting -ultralow in launch options
It's sad, but I may have to do that as well... Who says you need to upgrade PCs anyways?!? Graphics are totally overrated.
I bet the retro NES levels will look like Gameboy on ultralow, and Gameboy will look like someone drew the levels with a pencil and a piece of paper!
