Random bug fix

+ Ceiling climbing (test ver)

This action can be canceled by pressing "↓" (or other key depending on your control settings), reaching the edge of a shortcut or reaching the edge of ceilings.

Get extra half food point each time you complete mauling.This won't reduce the food amount you can get from corpses.
+ Slight movement boost
Slightly boosted sliding speed, rocket jumping distance and vertical air jump height (upside one).
+ Underwater discharge
You can commit large range fatal discharge by pressing "Jump"+"Pick up" while staying underwater. This ability has a small cooldown and may be op rn.
