major update (1.6.0)

• Weapon

1.  Added "Plasmagun" to the "Cell" category.
2. "Punch" can now be charged by pressing and holding "Fire". When charged, the flight distance to blow away enemies will increase.
3. "Hookshot" are now automatically cut when tilted more than 90 degrees from the camera's point of view. This makes it easier to fly far.

• BugFix

1. Fixed a bug that the mouse does not move properly at 30-60FPS.
