So, I found a bug... I don't know exactly what triggered it or if you've already found & fixed it in a newer version, but I still felt the need to share this. This happened on my first ever run and it went like this:
1: Zombie Battle. Got Infi-Nut
2: (Fork Path; top choice) Zombie Battle. Got Endurian
3: Shop. Got Fire Pea
4: Unknown Event. Car Shop (didn't buy anything)
5: (Fork Path; top choice) Unknown Event. Vasebreaker (Healed from 45 to 50)
6: Zombie Battle. Got Torchwood
7: Unknown Event. Evolutionary Leap (Converted one Peashooter to an Infi-Nut)
The next space I was going to land on was a "House" space, but when the UI for the previous "Unknown Event" went away, the House icon never un-greyed. I couldn't click on it, or any other tile, and the only thing I could interact with was the Deck Button and the Options Icon (everything in the main menu worked as well). Beginning a new run fixed it, but still a very strange bug.
I do like the game still. There's a LOT of potential in this, and I'm curious to see how many cards will be in the game at the end of the road!
