Bug fixes, Changes 6/15 ver.e0005bugfix2

Bug Fixes - Fixed an issue where performing a jump at the exact moment of landing after a double jump caused the player to lose the ability to double jump again. - Fixed an issue where the worn out jet pack behaved the same as the normal jet pack under certain conditions.

Changes - Changed the mechanics of the fist attack. Only the neutral attack now has a hitbox on the punch. The punch itself deals low damage, and when combined with the explosion, the total damage is roughly the same as before. This should reduce situations where the neutral attack completely misses and deals zero damage. If you want to deal high damage, you still need to attack at close range as before. When the player has the glove and the throwing enhancement potion, the punch range is now extended. The point where the explosion occurs also moves slightly forward. The neutral attack animation changes when enhanced in this way, although the difference is minimal. Explosions caused by punches now receive increased damage from explosion enhancing items, and no longer receive increased damage from throwing enhancing items. Instead, when the player does not have an explosion enhancing item, the explosion damage is now the same as when the player previously had one throwing enhancement item. In summary, the fist has been rebalanced: the enhancement method has changed, base explosion damage has been increased, and the damage area has been expanded. Overall, this results in a slight buff.
