Hey, Thanks for playing :)
Im sorry that it crashed. Weve already fixed a lot of those issues, but too late for the jam.
You are right. The description is something you always could improve.
The weapons like the Teeth (Marked with a W) are doing damage in some kind of way. In the Teeth case you should see that people equipped with that emit short range projectiles in high cadence.
The concept blood pressure is a little bit explained, but maybe not enough. Its just Currency income at the end of the round that does not work for Undead (your protagonist and franken Zombies).
There is an glossary that shows all possible items (The book button in the shop). But there is not more information than on the cards.
