Historical demo performance and the public-testing branch

The developer says October 16’s update can leave Reset failing to restore a level correctly. Its temporary workaround is Undo all the way back to the start, after which Reset should work. Long levels may need substantial undoing; the note promises no recovery of lost progress. Kingy has not tested this workaround.

The October 16 r67255 update addresses crashes or oversized save files after repeated resets following a pushed rock or redirected river. October 17 r67271 separately corrects a missing lily and transmutation/quit/re-entry character-switch failures. Do not treat these notes as verification of every older recorded route.

The October 14 update adds -graphics to override the graphics mode selected in the menu when that setting crashes startup. The note gives no argument values, so this guide does not invent a launch command. Keep the July demo beta settings and the later Proton fixes separately dated.

The July 10 post named public-testing, without a password, for the demo. It does not establish a current full-game beta. Only follow the historical steps below if that branch is still offered for your demo installation; record the actual branch and build.

1. In Steam, open the game’s Properties.
2. Open Game Versions & Betas.
3. Select public-testing if it is still offered.
4. Note the branch and build before reporting a problem.

The update documents a Very Performance setting, separate music, effects and voice sliders, and VSync, frame cap and anti-aliasing controls in Graphics. Try one setting at a time and compare the same scene; this is a diagnostic suggestion, not a measured best-settings preset.

The July 10 demo post reported improved compatibility with older graphics cards and lower-memory systems, no shader model 6.5 support at that time, and 60 fps in most Steam Deck levels. Those are dated developer reports, not measured release performance. The publisher separately announced Steam Deck Verified status on September 15; certification does not establish a Kingy-tested frame rate or preset.

The October 9 full-game update specifies SteamClient021 or Proton v9+ after a Steam SDK downgrade. October 12’s second update tentatively addresses E_INVALIDARG on Proton, Linux and Steam Deck/Machine. The publisher has not guaranteed every crash is fixed, and Kingy has not retested it.
