Wanted to give this game a try, but both using Firefox and Chromium, the book is completely empty for me. Looking into my browser logs, I get "Hidden/Universal Render Pipeline/Edge Adaptive Spatial Upsampling shader is not supported on this GPU (none of subshaders/fallbacks are suitable)", which I suspect might be the reason. Well, I guess it's on me for playing on a toaster. Too bad, looks like a cool game :)
