If you continue to have issues with movement there is now a reset button in the menu. Assign it to a key then press it in game and all relevant settings should be restored.
There is also updated difficulty, quick weapon switching, fixed grapple bugs where game would crash when spamming grapple button, and I added new man-bat sprites.
I know it's been about a year, but I felt so bad about these regrettable issues that were plaguing the mod, and I've been working hard to solve them. Thank you for your patience dear viewer.
