itch.io

Hi, the program (webapp) itself can’t do much, but depending on the operating system, you can share the contents of a window, the screen, or an OpenGL application (like a browser window if you have hardware acceleration enabled) as a camera. I can’t help you further without knowing the operating system you’re running, but some options are ManyCam (Windows, Mac), Webcamoid (Windows, Linux, MacOS) or if you are using Chromium (Chrome, Edge, Vivaldi, Brave, etc.) screen sharing also let you only sharing specific browser tabs, sadly this feature is not available on Firefox

what OS do you have? i can play properly even when running the game through Proton on Linux

if you are using OBS, you can set something like

html {
    background-color: rgb(0 0 0 / 1%) !important;
}

for some reason i don’t know, if you put all as 0 it shows black, if real transparency not working, you should try a chroma color, if color picker is not working properly, you should change it also via Custom CSS, as described on the manual:

html {
    background-color: #91a666; /*replace #91a666 with your preferred color*/
}
