Again Love your game Catapult Adventure Golf,thank you so much for playing my game and yeah about the error i get that error in all my games for some reason idk why :)
Thanks! Are you using a custom HTML page to embed your Unity games in? I wonder if it is looking for that default full-screen button Unity puts on the vanilla WebGL build HTML page (like on Catapult Adventure Golf).
Hm, I wonder if you could just hide it with CSS instead of removing it, so the code can still find the button. Neat idea tho — I've always just used the HTML file as-is, but you're right — it's better for embedding without all that other stuff.
You can try the minimalist format if you want, it as you say you might lose the loading scenes and stuff, I am. not sure about it I have. Not used it )
