And 90% of the time you can just skip to step 5 and that's your answer. Apparently giving you infinite cosmic powers doesn't make up for the fact that he's not a sexy cartoon girl so nobody likes talking to him.
- Talk to every girl in every outfit (all sex scenes in every outfit, all talks scenes in every outfit)
- Change your outfit (repeat step 1), repeat with each of your outfits.
- Visit BBB regularly
- Check the pen everyday (twice if there's something to draw)
- Talk to Yen Sid every chance (twice a day)
- Pay for all 3 upgrades from the dwarves on everything
- Visit all the attractions with a red ! except the one where the parrot is and the one with the lion neither of which you can fix as of yet (not telling you where they are so you have to find them at least once)
- Deal with the Villain's Tavern at night (last thing since most interactions end the night)
- Make sure to leave any girl who you want to proceed on scenes with um-assigned until you see all but 1 (last scene on almost all the girls is a strip show at the Night Club).
