A note from the developer
This is the very first public version of Arcane Idle, built by a single developer in their spare time. Much more is planned — new heroes, regions, crafting systems, story content, and quality-of-life improvements are all on the roadmap.
Your feedback shapes what gets built next. Thank you for being here from the start.
