I can see the inspiration captured from Inscryption and Buckshot Roulette as listed in the GDD perfectly. Nailed down the shadowy vibe and somewhat spooky vibe. Big fan of Inscryption. :)
I got a weird bug after using a double harm effect and force potion card in the same turn. First the opponent at 3 hp drank it and dropped down to 1 hp as expected but when the opponent drank another normal harm potion, instead of the hp dropping to 0, it went back up 1. Other than that, the gameplay loop was clean and varied between too easy to a little bit challenging at times depending on the cards and ingredients gotten from RNG.
