Additions:
- Mouse X and Y invert options
- Mousing over the challenge button of a completed level in the level select screen now shows the challenge of that level
- Added the framerate target option that defaults to twice the current screen's refresh rate to improve performance and fix some physics errors
- Made projectile boosting (aka "shotgun teching") from a bug into an official feature, making it work more consistently and removing the style gain unless the boosted projectile hits an enemy as well as removing the health gain
- Added new performance options for disabling environmental particle effects and simplifying enemy spawn effects 

Balance changes:
- Added 3 mercy frames between a projectile hitting the player and the damage happening, making projectile parrying slightly more lenient.
- Changed projectile parry from a raytrace into a hitbox, making projectiles a bit easier to punch at an angle.
- Added diminishing returns on healing a lot in a short period of time to disincentivize tanking hits, though this shouldnt be enough to affect anyone who isn't
- Cerberus can no longer be cheesed by standing on top of its head in a corner or by standing on the pedestal they start from 

Other Changes:
- Made texture warping a slider rather than a toggle
- Made toggles in the options slightly lighter so they're more easily visible
