I've had people play IdleQuest on tablets and Steam Deck but I'm fairly certain it would be horrible on phones.
How is this not going to get sued into oblivion by Sega? Especially using your real name with it.
That being said, I tried it on Firefox and just got an empty blue screen after the level loaded.
Sorry to hear about bluescreen, I haven't had any other reports of that from other players. Do you have resist fingerprinting turned on? It can mess with WebGL games a lot.
