Milthm

Milthm is a free-to-play rhythm game that launched on November 16, 2023, and has been receiving consistent major content updates ever since. The developer has shipped 9 major updates across roughly 2.5 years — adding new music tracks, gameplay modes (such as "Garden," "Lustrous Dream," and "Nightmare"), story chapters, online features (leaderboards, replays), and full UI overhauls. Key milestones include Version 2.0 (August 20, 2024), which overhauled the entire UI and added Main Story Chapter 1; Version 4.0 (September 25, 2025), which introduced Side Story Chapter 1 and two new gameplay modes; Version 5.0 (February 25, 2026), which added online leaderboards and replay functionality; and most recently Version 6.0 (July 22, 2026), which added Main Story Chapter 2, introduced the Lightning Note as a new playable note type, expanded the Garden mode with a new Mutation mechanic, and shipped two new tracks. This establishes a very consistent pattern of major updates arriving roughly every 1–3 months. As of today (August 21, 2026), only one month has passed since the last major update — well within the established update window. The developer has not signaled any conclusion to content development, and the ongoing story content (with Main Story Chapter 2 just added) strongly suggests further chapters are planned.
