Hmm, I bet the problem is my code expects touch events instead of mouse events when a touchscreen is present. Unfortunately I don't have a computer with both touchscreen and mouse here to test with so I didn't test that case. I did implement both gamepad and touch controls, so you could try them to see if they work.

Same browser on win10. Mouse works after you click in the window and it goes full screen. However, it hangs after a few seconds of game play.

Stopped hanging... then input locks up somehow.

Switched to chrome on win10, same issue: input locks up after a bit.

Yeah that issue I have seen, but unfortunately haven't been able to debug yet as it isn't very reproducible and usually stops happening under a debugger.

Even with the problems, just the few seconds of playing before the crash+input hang got me hooked. So, off to GOG to get q3a for $15. Also, quake3e with all the quality, widescreen, aspect ratio and FPS tweaks... chatgpt 4o seems to know everything there is to know about quake3e, for some reason.

Talk about getting nerd sniped.
