I thought I was able to beat the system by making a full gray deck and kept going all in. I think I got too cocky though, because I lost to an all in...
It's a very balanced and polished game, the scaling stats for both the enemies and the cards make a long gameplay that doesn't bore easily.
I really like the ambiance and the general aesthetic that was given here, like the bizarre enemies and them having personal traits that define how they play.
The only thing I'd like to point out is how hard it is at the start to understand what the game wants, but after you get the hang of it it's great and it has an entertaining game cycle.
Gooj job!
