maybe i just suck, but i'm struggling immensely to manage anything resembling progression in the endless. some cards seem to accomplish next to nothing against the npcs, but are brutal against the player. The "prevent endurance loss" stretch cards in particular seem to do that.
The base here is solid, but the gameplay feels like it needs some tuning. I can't get out of wave 0 in the endless mode, i don't know how other commenters managed to get far enough to break the game.
Edit: the skill point system is pretty hidden, i only caught it when the system gave a point, didn't know it existed prior to that.
I also suspect pressure point isn't working properly, a 20 nausea dot that seemingly can't be dispelled AND gives upside to other card by turn 3 seems really excessive, especially since it only drops 1 stack per turn for that damage output
