Clea

Clea launched on July 10, 2019 and received a healthy run of post-launch updates over roughly two years. The developer added new difficulty modes (Chaos+, Arcade, Invisible), a 1-Ups accessibility feature, multiple unlockable costumes, and finally War Maiden Mode — a challenging endgame mode that shipped on September 13, 2021. That War Maiden Mode post explicitly described it as "the final, ultimate test of skills" and there were no further content updates to Clea after that date. From late 2021 onward, InvertMouse shifted full focus to a new project internally called "Project X," described as the spiritual conclusion to the Clea universe. The developer has posted updates about Project X's progress in October 2023, July 2024, and December 2025 — but all of these confirm that Project X is a separate, standalone game, not additional content for Clea. The July 2024 five-year anniversary post celebrated Clea's legacy and previewed Project X, with no mention of any remaining Clea content. The sole DLC on record — the Anniversary Artbook — released on July 13, 2020 and is fully available. No unreleased DLC exists. The game's content is complete as of the War Maiden Mode update in September 2021.
