We've just added a WebGL build that should run on all modern platforms and browsers. If you get chance to play it before the votes end that would be great, otherwise please feel free to feedback to us after the voting period, we're still really keen to get people's opinions on Scuba Squad.

The only real changes were to do with making the fonts larger and bolder so you could read the text when the game runs at the default itch.io WebGL page resolution of 960x540 (1/16th of the 4K resolution we designed it for). We did bug fix the Demo Mode not working as well. Lastly, the level meshes were being generated using compute shaders at runtime so we had to export those to static meshes and bundle them with the build to get it working on WebGL.
