Well you didn't lose much, as I got only technical demo out, and bad one too :D
May I ask which browser did you try? The WebGPU support still varies a quite bit between browsers.

I had previously tried it on Mozilla Firefox, however I tried it again on Chrome now and it worked this time. It's pretty cool. I didn't know what a lot of the variables were for (debugging was my guess), but the compute shader stuff was impressive. Not really a game, but this was neat to see something that I've never personally experimented with before.
Yup that solves it, thanks! Firefox doesn't have WebGPU implemented in regular version. Opera and Chrome supports pretty well. I should mention this on the page.
Yeah listing was mostly for debugging, but also showcasing that I can read now device limits etc. which you can't get normally easily in GameMaker 😌
Well although I couldn't make game in time, I got pretty solid system out of it 😄
