Evaluation

Poly Universe is a solo-developer Early Access city-builder that has been in Early Access since July 20, 2018. During its active period, the developer (Pouchmouse) maintained a consistent pattern of meaningful updates: a major story mode overhaul in January 2020, building upgrades and research improvements in June 2021, and a full interstellar trade and galactic map overhaul in December 2021 — with regular feature patches and bug fixes in between. The December 2, 2021 update post (NEWS-1) is the last communication from the developer. In it, Pouchmouse explicitly promised a procedural planet generation update "early in 2022." That update never appeared, and there have been no news posts, patches, or developer communications of any kind since that date. As of June 27, 2026, the game has been silent for approximately four and a half years — far beyond the roughly 4–6 month cadence between major updates that characterized the game's active development period. The game remains available for purchase on Steam with its Early Access flag still active, meaning it has not officially launched or been delisted. The store description still reflects the game's current feature set with no mention of a 1.0 roadmap or completion timeline. With an outstanding developer promise unfulfilled, a multi-year communication blackout, and no explanation provided, the current status of development is genuinely unclear.
Evidence
Developer shipped the Starmap and Interstellar Trade overhaul (v0.9.4.21) and explicitly promised a procedural planet generation update 'early in 2022.' This is the last communication of any kind from the developer.

About this game

A tiny band of settlers land on a remote planet. With you as their leader they will either build a new civilization, or be consumed by the foul creatures which inhabit the furthest reaches of space.

In Poly Universe worlds are tiny but numerous. Be strategic in laying out your cities to maximize the limited space available on each world. Balance industry and residential buildings to keep your citizens happy. But don't neglect the defenses necessary to keep them safe! Here in the outer edge of the known universe, danger can arrive at any moment, and when it does it arrives in full force.

Establishing trade routes between worlds will allow your planets to specialize and share resources, pushing the boundaries of your civilization even further outwards. But always keep an eye on the health, happiness, and education of your citizens -- with nowhere to receive reinforcements from, your citizens are ultimately your most valuable resource.
