July hotfix #8

Long time no see. List of changes:

• You can now use custom-palettes for Fern.
• Fixed mech leg animations being weird(This code is still horrible but I'll never fix it lol).
• Fixed mech gravity and friction
• Reduced hook pull on enemy to 38%(It was really powerful before, enemies just had weird interactions with it, with those fixed the hook would throw enemies across the screen)
• Hitting enemies close to you works again 
• Added some juice to hitting enemies
• Fixed some room transition bugs
• Removed rng with enemies charging speed(Enemies used to have 0 to 1 second delay on initial attack. now it's always .5 seconds) Fixed some hook ailment issues Improved performance a bit
