Hi,
I'm Mario and creator of "LambdaRogue: The Book of Stars", a roguelike RPG (which I uploaded to itch.io yesterday, but the game is in fact much older (2006-2012)). Currently I'm working on a text adventure made in Twine (a crime/mystery story).
I also work in flight simulations (maybe you've heard of the X-Plane flight simulator, for which I co-develop airplane addons for vFlyteAir), and write essays and books about communication & society (all in German language).
