- Patch 1.5.17 - 19 August 2026
Unfortunately the upgrade to Unity 6 resulted in some old solutions no longer solving correctly. Although we tested old solutions as part of the engine upgrade, we didn't catch some cases that our users have reported. It's more important for us to keep previous solutions working for our players than to upgrade the underlying engine (which was a nice-to-have, not a necessity). So we have rolled back to the older version of Unity, while still keeping the other improvements and fixes from 1.5.16. Sorry for any inconvenience, and thank you to our players for reporting this problem!
- Patch 1.5.16 - 18 August 2026
Poly Bridge 3 — Engine Upgrade & Fixes We've just released an update for Poly Bridge 3. While most of it is under the hood, it's a big one: the game now runs on Unity 6, the latest version of the engine. This keeps PB3 on a modern, supported foundation and brings updated rendering internals along with it. You shouldn't notice anything different, just the same game on a healthier engine. This touches nearly every part of the game, so if anything looks off after the update, please let us know! Improvements When moving a node, highlight edges in red that constrain node movement The gamepad cursor no longer shimmers along its edges while moving Performance optimizations Faster asset loading Fixes Mute and Mute In Background now take effect immediately when toggled with a keyboard or gamepad (previously they only applied when clicked with the mouse or after closing the menu) Canceling the on…
