Factica

This of a demo of an attempt at a turn based role playing game, originally released in 2022. 
In it, you battle an opponent by quizing. You are presented with a question inside a category and if you happen to hit the correct answer, the dice rolls and a number is calculated, that is then subtracted from the opponent's total hit points. And if you hit wrong answer, then you are loosing hit points yourself.

It also features some "local multiplayer" in that sense, that you can play against your friend next to you on the same computer, by taking turns to anwser a question
