Could you describe that more in detail? I can't seem to replicate that bug on my end
It didn’t happen for me but it has happened with other games. I’m on mobile, IOS, using Brave browser, I don’t know, but i think it might be a glitch with the game or itch/browser not registering the game as closed, though that might not be it. I play the games on a separate tab with the game list still open, but even with all itch tabs closed it will still play, only when this issue happens. Hopes this helps in some way. :)
