Update v0.8.4

Adding a tactics component to a deckbuilder means two new avenues of defense: moving out of enemy range, or taking aggro with another unit.
It also adds new restrictions on offense: your own attack range, and line of sight.
This naturally led to more defensive play.

For a while, I was thinking of a way to reward aggressive play to balance this out.
This update, I'm trying a new thing where the faster you finish a battle, the more Stars you get.
Please let me know how this feels!

Also, the third layer of Curses is implemented.
Also, the third realm should feel much different in terms of build choices.
Also, the story continues.

Rather than re-format the changelog for Itch, I'll just link the Steam changelog here for details: https://steamcommunity.com/games/3608900/announcements/detail/594040207780611240
