Evaluation

Costume Party launched on December 27, 2021 as a free-to-play adult simulation game. Since launch, the developer (SinVR) maintained a fairly regular pattern of updates through mid-2024, including feature patches (new animations, improved VR controls, camera improvements) and cross-promotions for new titles in their portfolio. The store description explicitly states "We promise to update this game regularly, with more characters!" — a commitment to ongoing content additions. However, the most recent developer communication tied to this game was on May 21, 2024, and both of the most recent posts (April 19 and May 21, 2024) were actually announcements for a new, separate title called Fetish Club — not updates to Costume Party itself. The last substantive update to Costume Party's own content appeared to be the August 2023 moving heads feature patch. No communications have been posted since May 2024. Given the developer's prior posting cadence of roughly every 1-3 months and the explicit promise of ongoing character additions in the store description, the silence since May 21, 2024 — now exceeding 13 months — raises genuine uncertainty about whether active development is continuing. The shift in the developer's announcements toward new titles (Bambie!, Futa Tales, Fetish Club) may indicate resources have been redirected away from Costume Party.
Evidence
Last developer post — an announcement for a separate game (Fetish Club), not a Costume Party update. No Costume Party-specific communication has followed.

How did you get to this crazy hotel in the first place?

And how do I leave this Hotel? I’m not back in California again, am I?
