QA passed ✅
Build: 4b879f4

Scene: flutterecho

Single player works ok for Windows and Mac ✅

Multiplayer: ⚠️
The issue #7275 discussed on this thread still occurs, and I was able to test that the workaround work. However it's a bit confusing for the user. In my case, I didn't know I had to go through the trigger area again to get unblocked.

As for this issue #7290, it's related to 7275, both in steps to repro and workaround, so I closed it to keep all discussions in 7275.

Multiplayer:

multiplayer.windows.mp4

multiplayer.mac.mp4

Workaround:

16.03.2026_10.35.17_REC.workaround.mp4

Conclusion: everything functions as expected in both single and multiplayer modes, except for the tunnel force-up and force-forward. Although there is a workaround, it's difficult for users to figure out how to unblock themselves.

It's been decided to leave the issue as known and communicate this to the creators.

Single Player windows:

PR-7044.single.player.mp4

Single Player Mac:

16.03.2026_10.05.12_REC.PR-7044.single.player.mac.mp4

Double Jump + Gliding was tested and works as expected, evidence here.
