I got my first Dark Lord girl early this morning, quite happy about the hefty boost to my income XD
Also boosted Bunny to max affection, 30 minutes is still awfully short considering it does not accumulate, so leaving your computer to go out with friends/go to work/sleep/etc. causes you to lose a lot of income. Granted the game's content offering right now is small enough that this is not a huge issue (no real rush to get through Area 3/gather lots of girls ASAP)
