Hi! I'm Jacob!
jacob@yupcup.games
I'm a system designer, programmer and artist based in Oslo.
I started developing games as a hobby when I was 10 years old, and I've never stopped since.
I'm particularly inspired by systems that create situations far beyond the sum of its parts.
e.g. Mosa Lina's everything, Breath of the Wild's element simulations, Arc's ambitions
I'm also interested in games with streamlined systems that lead to much more potent gameplay.
e.g. PEAK's energy system, The TTRPG "A Sliver of Fate"'s lack of health - instead losing parts of your character
Lastly, I'm a big fan of weird TTRPGs. Get in contact if you want to play anything!
Favourites: Grok?!, CAIN, Mothership, Downcrawl, Itras By, Fate Accelerated
