The game that shows up for me doesn't seem like the game in the photos nor what other commenters are describing. After pressing "start" on a white intro screen, the game starts for me with a black screen and dark-gray descending platforms that I can jump around on. The black screen and gray platforms continue for a few minutes until, for an unknown reason, the screen fades to white, a clock descends from the upper-left corner to the center, and the game resets. The clock seems to be in the upper left corner the whole time (though black numbers on a black background), because when my character moves into that area, I can see it silhouetted against the white clothes. There also seems to be an occasional message at the top of the screen, because I see letters silhouetted over my character at times if I jump to the top. But other than that, I can only jump around on platforms in darkness until it ends.
Oh daaang that sounds like a huge (and very mysterious) bug. Very weird. I'll definitely try to figure that one out! Thank you for letting me know! Yeah after clicking start, the screen is suppose to have a white background, and you jump around on platforms.
Maybe the bug is because I used WebGL3...
Update: I was playing it in Firefox when I had the black screen issue; when I switched to Safari it worked great -- and it's a great game! I loved the artwork and your colliders on complex surfaces functioned very smoothly. It was a fun game to explore -- nice work! (In case it's helpful for debugging, I've played dozens of in-browser games from this jam in Firefox with no problems. There was one game where a functionality in the game didn't work for me, but I just now went back and tested with Safari and it didn't fix that issue, so unrelated).
