If I enable the gamepad before Goku jumps Snake Way and goes to King Kai's world, the joystick will disappear, and I will need to re-enable it for it to return. I posted a video in the chat.

I need clear information about your phone, your browser, your browser version, how many tabs are open in it (= memory leak)....
Because I can't reproduce your bug.

Also what is the size of your screen ? It seems to be very small.

Does the joystick reappear if you turn the screen in the correct horizontal direction?

Samsung S22

1 tap

C'est bon, j'ai réussi à le reproduire.
En même temps, si c'est simplement réparé en cliquant de nouveau sur le bouton gamepad, ce n'est pas hyper gênant, et donc pas pressé à régler.

This should work now. Please try and confirm.

Yep it works 🙂
