I really enjoyed this one! Even though the corruption is actively spreading, I like that the game encourages players to go at their own pace and think critically about their next moves. It makes for a relaxing yet engaging experience!
I think some sort of visual indicator for when we have a card selected would be nice to have. As of right now it's a bit difficult to tell when I've properly selected one of the cards and can place down a tile.
Other than that, nice work!
