Lautta
We tested this route on a development Mac. Lautta’s public installer is still being prepared.
What was the problem?
Our earlier Wine and WebView2 experiments produced a white screen. The exact cause of every failed attempt was not isolated. Inspection showed that this game includes a Construct web archive in its original files, which gave us a different route to test.
What did Lautta change?
Lautta reads the owned game’s original www/assets.dat without changing it and opens the Construct content in a native macOS WebKit helper. A game-specific save adapter keeps progress in Lautta’s local save area. The packaged Lautta Play action now starts that helper.
What did we verify?
In the earlier native WebKit test, the tester confirmed visible gameplay, audio, controls, saving and resuming after relaunch. A later packaged Lautta Play check confirmed that the title screen and menu appeared. The full gameplay and save sequence was not repeated in that packaged check.
What remains unverified?
This is a local development result, not a public install guide. A 30-minute continuous session and a clean installation on another Mac remain unverified. Lautta has no public installer yet.
