Congratulations on your first game!
If you click load game without a saved file you can't go back.
I didn't understand why the MC became a sorcerer or why he could steal money with portals, but porn logic I guess.
The game needs a tutorial, first thing I did is end day and I didn't even know that.
I think portals should close and open automatically.
There's no point to the days system, I guess that could limit the portals you spawn per day.
The only lewd scene is at the start, and it's not with the MC.
There's only dialogue with the apprentice but it's incomplete and bland.
The woman model doesn't look like a sorcerer aprentice, she looks like a secretary.
For a first try it's okay, you have the base but it's very incomplete and I can see it suffering from scope creep, becareful about not cutting enough content because a full release of this I can see taking a year or two, good luck!
