I'll be honest I mostly played this because Pendleton Ward did the art and let me tell you the art is superb. Game itself didn't really hook me much so I dropped it.
When this game works well it's addictive, strategic, and entertaining, but when it doesn't it induces hair-pulling frustration. Card of Darkness is just ruthlessly balanced when it comes to randomness -- there's no guarantee that a given board is even solvable. Compounded with some challenging to keep track of enemy effects, I often found myself in no-win, frustrating beyond belief levels. The game still has a lot going for it in terms of charm and interestingly strategic gameplay, I just wish the randomness felt a little bit more fair.
Pretty addicting card game. Enjoyed the art for the most part. Would play another Gage game!
