Zero Stress King: Idle Defense

Zero Stress King is a relaxing incremental dressed up as tower defense. Enemies keep charging your walls, but there's a river of lava in front of them, and every single one falls in. You can't lose. Your part is hiring defenders and raising production while the waves keep growing. Your map of conquered land is also your skill tree, so spending points is how you push further out. There are no failed levels and nothing to restart. The game is about numbers climbing while enemies keep running into the lava. It's short and came out on Steam in March 2026 from Pauloondra. It suits anyone who likes the look of tower defense but doesn't want the stress, or who wants something calm to leave running while the counter goes up.
