Thanks for trying it. Do you mean embedding the game in the page directly instead of the click-to-play launcher, or something inside the game itself? Tell me what you saw and I'll try it.
I think I get it now: the game sat behind a 'Run game' button instead of loading in the page. I've switched all seven of my games to load straight into the page on desktop (on phones itch still shows its own launch button). Thanks for the nudge.
