This game is great so far! I look forward to seeing what all you have in store! I especially like Iris, and the slime scene she has. Personally I enjoy monster on girl scenes with slimes, tentacles, a group of goblins, etc. I also would like to see some scenes of Iris with other men and women, and if the story has plans for decision based choices that affect the end result, I'd love to see an ending where Iris gets captured or enslaved and Vincent abandons her, or Iris chooses to leave Vincent and forsake the exam so she can stay with the monsters and people in the cave.
Also that bath scene is nice, but could it be possible for Vincent to decide whether or not to join her, peep on her and Adda (the cat girl that sneaks up on you in the bath) having fun, or forgetting about Iris and having something capture her?
Sorry if my suggestions are lofty, I just really enjoy this game so far.
