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
