Idle Slayer

The verdict
A pixel-art auto-runner welded to a soul-collecting idle engine, with an Ascension tree deep enough to reward planning. Cross-platform cloud saves, 600+ achievements, and a solo dev who's still shipping major updates six years on.
Hot take
The active/idle balance is the secret — tap in for the boss rushes and events, walk away for the grind, and it never punishes you for either. Rare discipline for a one-person project.
