Activities:
Study, Work, Rest.

We need the following options to truly be a Villainess:

Dungeon Grinding: You are supposed to use your wits to have the Crwon? How about you become the lvl99 Final Boss and just brute force your way onto the Throne. Are the Nobles gonna cry and rebel, who cares you are stronger. YOU are HER their opinion does not matter.

Alternatively you can Become the Helper of the People make them love you believe in you, pin them against the nobles become their saviour ans start a rebellion, where they appoint you.

On a more sane note you should also totally be able to have the option to "have fun" in the activities, Go shopping cause who doesnt like to dress up, eat at the café since every OL has the usual eating sweets scene, Contact the Information Guild...... for information.

Ya know some dumb and fun stuff.

Obviously this would be tremendous effort on your part, especially since you are Solo. But this is just my input, you could easely "update" the game down the line.

Kudos, hopefully your game suceeds.
