Descriptive Popups (v0.3)

My newest update from the feedback I've received! This one focuses on providing mechanical information about the creatures in play.

Main changes:

• While hovering over a creature, press "i" to open the creature stats window and see all the currently relevant information about the creature. (Click off window to close)
• While hovering over certain gameplay terms, a popup will appear by the cursor describing the term's mechanics.

There is still much more to get done, so stay tuned for the next update!
