I think the polish and aesthetics is very well done. Managed to get to round 8 on hard mode. I think maybe providing a guidebook on what an enemy's actions do would be great, especially cause I'd find myself forgetting from time to time and some look very similar to each other. (This is also important cause hard mode starts with the random action card, and using it I'd be like "What the hell is this.")
I think mechanically its very simple but there's a lot of depth and overall it's a blast! Imo, I don't know if this is a hard thing specifically, I do think making players also have a chance to randomly get a cursed potato is REALLY toxic form of difficulty.
Great job though, loved the hell out of this game!
