ObsidianKey is a vertical skill carving mobile game that combines precise grinding and rune matching gameplay. Players slide the silver engraving knife to carve the obsidian mold, compare it with the floating light array to create tooth marks, and adhere it within the time limit to prevent the crystal from cracking. They can challenge for higher scores in increasingly difficult levels, making it easy to get started while also being highly strategic.
ObsidianKey is a skill-based mobile game.
