Sorry you had such issues with the controls :(
I honestly have no idea what could be causing this, especially since it’s my first time making a first person game.
But since you said this seemed to happen with multiple other web gl games this could be something on your end ?
Not sure how i could help with this, best guess i’d say would be to check if you have this same issue with every web gl you try, regardless of engine, and bring up the issue again to see if maybe other devs would know more about what could cause this.
Sorry again about this and that i couldn’t be of more help, hope you’ll find a way to solve this :/
