Please ignore my angel coment I found them
You could have more payment for the beast-demon trade route (I payed 200 coins for this and all i'm getting back is roughly 15 coins a time)
Maybe have the player have a main goal (maybe become one of the princes of h#ll or see and defeat angels)
Also (last one), I hired mummys. Mummies go away. Mummies did not go away and came to me to go away again. And again. And again again.
Also lost goblin after not being lost became lost again
I marryed Goblin, Milia, and beast-prince in one game?
