I have played the game for almost 5 hours now. it did take about 30 minutes to fully understand everything, which in my opinion, is not bad at all. did reach king difficulty relatively fast.
However, the King of Blood's perks are lacking imo, either that or i just could not think of a viable option. I can on average get to year 18-20 with ease but i just get swamped after that.
Will say the game is very addicting though, and am most likely going to pick up the full game when it releases on steam. easily a 7.5/10 with room for upward growth!
