The Heads Behind Leif's Adventure:

Roman Fuhrer

OneManOnMars Founder and the Creative Mind behind Leif's Adventure

I’m glad you found your way here. Leif’s Adventure has been my heart’s project since I started planning it in 2016. Since then I’ve been working hard on the implementation of all ideas, be it game design, graphics, story, animations or all the managment duties that come allong of beeing an enterpreneur. I even learned how to program to make my dream of a game for the Nintendo Switch and Steam come true. I hope you enjoy playing Leif’s Adventure – why don’t you just try out the current demo? And although I started this project alone and did a lot of things on my own, nothing works without the right support. Some friends have helped me make Leif’s Adventure and I’m especially glad to have Jan and Patrick help me on this journey.

Jan Schaumlöffel

LTT Bird // Sound Design

Jan joined the project quite early on and helped defining the sonic vision of the game. His work includes asset creation, implementation via audio middleware FMOD and audio programming.

Patrick Henschel

Unity Developer and Engineer

Patrick joined a bit later but whenever code gets complicated he is the one to make Leif’s Adventure do what it should and keeps the code proficient and fast.
