Another teeny update.
- Added prompts that appear when the player tries to use a card but cannot. (Should aid with onboarding & new player confusion.)
- Fixed a text issue on the sidebar (Garrison was not plural)
- Reduced the cost of the highscore challenge from 32000 to 30000. (Not retrospective, sorry.)
- Slightly reduced the rate of enemy HP gain over time. (3x to 2.75x)
Thanks for all your support!
