First off realy good game so far has a solid 3 to 6 hours of game play befor you run out of events. I liked that you can't scum save the card game. It would be cool if more girls had their own mini game you could play with them in the evening to get money, increase affection, re-see an echi event.
Making some random repeatable events seems like a good idea as when the main events run out the only hot thing you get to see is your monsters (gets old fast), while min maxing monster skills and stats by hitting the skip time over and over is kinda interesting a bit of selectable variation would be nice.
After male monsters show up it gets realy disorganized. Could have an entirely separate tab for males and should have sort options for race, level, skills. Needs a favorites/lock button for monsters you don't want to sell. Needs "are you sure" window pop up when hitting remove monster from the barn. Explain the orderbord at some point. Needs skill descriptions...
A lore book would be nice, one that kept a record of the world history you learned, gave characters biographies that unlocked more info as you progressed. Bestiary of interesting information about each monster things they like/dislike, how to take care of them... average sizes of their various assets ;) Could put skill and tutorial information there too.
