Heyo, I'm gruebite, and this year I'm making Aurumorium!
Aurumorium is an incremental mining roguelike where you carve your way through walls in an endless cavern. You play as a golem powered by pure avarice (and a philosopher's stone), transmuting walls into gold which you spend on forging evermore destructive cantrips. You're under the command of an alchemist who periodically imposes a tax, both a flat fee and a percentage, on the gold you've collected.
The idea is inspired by one of my favorite dungeon generation techniques: the humble random walk. Early in the game, you'll be slowly carving your way through the cavern, but as you collect powerful cantrips, the golem will be blitzing around, unleashing a cascade of satisfying effects. My plan for cantrips is pretty simple and should accommodate both order and chaos.
Good luck, everyone!
