Not a bad start. few things i had issue with was during combat the 5mp attack sometimes did more damage then the 20mp one.
if you're going to give us a spend-y attack, might want to add like a stun or a stat drop to it to make it worth choosing.
Also when confronting F.F. he mention Psi Master had already been beaten by someone, but during the lair tour Psi Master never alluded to that, might want to change the dialogue a bit and make it so P.M. is actually a rookie supervillain, not an experienced one. Might also make his rule/conquer dilemma more believable and a great running gag.
When after successfully hypnotizing F.F. you get asked to choose what kind of slave he is. Would it be possible to instead add that to their talk menu as a kind of "mode change"? Would probably save you a lot of writing later AND would be an interesting game mechanic.
Example: you take him to your playroom and initiate playtime. He automatically switches to kinky mode so you only have to write kinky mode dialogue for him.
Mechanically, you could make it so that different modes give you better bonuses against other supers. for instance, a super that's weak against dirty talk or kinky displays against a party of kinky mode villains. or a hero/villain that can disrupt your mental hold so the solution is to turn off your party thoughts with drone mode.
Also might want to change the "Heroes" on the lair panel to "Supers" since you'll prolly have to go against other villains as well. The more the merrier right?
wrote more than i thought, but its got a LOT of promise, looking forward to more
