True. A lot of work is still ahead.
Regarding boss, games like this usually rely on building your imba deck. It requires a bit of planning and luck. I managed to get my imba via maximising lewdness and using a card that depends on it. So I had smth like 25dmg 25pp for 1 action point. You'll also require that card that takes N x 10 lp from you. Unfortunately, the game is low on content and balance is not there yet, but at some point I believe you'll be able to beat the game with different builds.
