The achievement system was removed, mostly due to most of the achievements coming from killing yourself in some fashion. In lieu of that a boss rush, I have allowed for unlockable cutscenes.
Glitchmethod was replaced with Starwind, and BigWimply was replaced with RoundTheWheel.
The game layout has been edited to make for a better difficulty curve and to try and close some loopholes.
There is now a language filter option to make the game more stream-friendly, but you can still turn on the blood and swearing if you desire.
Bosses have been nerfed to be more reasonable (especially Glacius,) and weakpoints have changed on some.
