EHG Patch notes 0.59

this is what is hopefully the final major design change to the game, there's a lot of stuff, but here's the key changes (read:):
* change: upgrades stack up to 7 times per hand, instead of 8
* change: projectile size upgrade now affects weapons too (upgrade name will be changed eventually)
* change: level selection overworld is removed
* change: multiple bosses are in the same world, this changes the design of the game in a way where you go to the enemies, instead of the enemies coming to you, this opens up more fun moments in the game, and makes the game less one dimensional
* change: trees and grass are now being culled if they are not visible on the screen, should help with performance
* change: you can keep holding space for higher jumps
* change: casting grappling hook as a heavy attack will now pull enemies at you
* change: gravity becomes snappier after falling for a while
* change: quality settings now reduce the amount of triangles in the terrain, should help with performance problems on low-end devices
* change: dragons scale is smaller so youre not just punching at its feet during combat
* change: dragons jump hole is not as steep
* change: item duplicates now offer the option to upgrade
* change: interacting with many items on the ground now opens up the inventory for better item management
* change: camera behaves differently when powerup is active
* bugfix: enemy rock affectors can now be cancelled properly
* bugfix: harold no longer gets stuck in a loop where he is trying to eat rocks
* bugfix: various minor performance improvements in the animation code
* bugfix: transition animation when durco recovers from a knockback while in a punch animation
* bugfix: rotation bug with sandworm that was causing the sandworm to attempt to roll away when quickly punchin it 3 times
* bugfix: shockwave now impacts feet instead of the root of the character
* bugfix: club damage now scales with damage in your stats
