Pongo

Pongo launched on May 11, 2015 as a self-contained 3D action platformer with 45 levels, bosses, puzzles, and an original soundtrack. The developer posted a handful of small patches and announcements in 2015–2016 — adding achievement stats, mouse look inversion, a new soundtrack, and announcing plans for Mac/Linux support and a Soundtrack DLC — but the last developer communication of any kind was on May 15, 2016. There have been no posts, patches, or announcements of any kind since that date. The Soundtrack DLC and controller support that were announced in May 2016 do not appear to have materialized based on the available information, and with over a decade of silence since that announcement, there is no meaningful expectation of future content. The game shipped as a complete, finite experience and has shown no post-launch content cadence. It is best understood as a finished product.
