- Made bosses weaker

- Bosses shouldn't charge as often now, they can take breaks in-between charges as well

- Fixed a few sandbox bugs

- Changed the animation for Imps getting zapped to make it clear

- Made treasure yeti have less health, for some reason plants ignore him and idk how to fix it so he has less health now. The plants usually hit him anyway when aiming for imps so it should be fine...
