Hey, thanks for playing our game. We appreciate the feedback, one of the big things we want to improve is communicating how to play to the player. The idea is you mine rune ores with the space key. Once you have the ores you can craft new runes over at the crafting table. To craft, click on one of the runes, one click crafts one rune. You can turn in the runes to the patrons in the shop, they'll let you know if you have enough runes. We're going to take the time to improve this game after the ratings period for the jam, it isn't in a state we wanted to leave it in.
