Things I would like to see in this game:
-I wrote my thoughts on your last game, Screamer. Those thoughts still apply to this.
-A fast travel system that is free/inexpensive
-An option to save AFTER beating a boss but BEFORE choosing to spare/tickle her. That way I don't have to retry the battle just to see the alternative.
-The brothels or tickle buildings were very cool in the last few games. I want another one or two of them here. There were a lot of cool ideas: resist tickling a girl as she taunts you, tickling scenes with specific body parts, girls that tickle you, that tickle researcher, games, etc.
-A few more detailed bad ends. Maybe even a some silly ones like picking a weird option in a town / tickle building.
-the Boss Zone, yes.
-an item you can equip that gets rid of random encounters while wearing it(if those are in this game).
