Thanks for playing.
The diamond puzzle seems to be problematic for some players. You need to spin the disc to lift the portcullis, then quickly get up there and walk out with the diamond before the portcullis closes.
Also I see you had some graphical glitches, but I guess it depends on your Linux environment. I had one friend test this on desktop Linux and another on Steamdeck and it was fine in both cases.
Ye, the game warned me about the potential for glitches ("you have driver version 2.x.y, we recommend at least 21.a.b") so I have nothing to complain about. It may be that it needs the amdgpu-pro driver.
Perhaps the portcullis could be somehow visually connected to the disc, I though the disc was supposed to help you do a cool movement trick but could not figure it out. Oh by the way I really enjoyed the air controls / movement style!
