I just competed in my first game jam! I made two submissions to the Borders One-Page RPG Jam 2021.
My first submission is Through the Borderlands. Players take on the roles of waldborne, an ancient wood-folk, fleeing a plague that changes victims into ravenous monstrosities. The players are trying to guide the survivors through the deadly Borderlands to the safety of the Western Imperium and its rune-warded walls.
The second submission is I Stab at Thee!!! I describe it as a sort-of-micro-role-playing-storytelling-improv-card-dexterity-party game (or SOMRPSICDPG). One player is the villain who has set his ship to self-destruct. The villain player monologues about evil stuff and their petty gripes against the crew; meanwhile, the crew is trying to repair their ship to escape the explosion.
