Something happened, and I couldn't control very well with my mouse... :( It kept either rotating and a crazy speed (perhaps mouse sensitivity), or the mouse would leave the game screen and made difficult for me to turn, so I kept dying.... :(
I am so sorry about that! Godot's HTML5 exports are notorious for breaking mouse capture if you click during a loading screen or hit esc during a game. It's an issue I'm still trying to find a foolproof fix for. Thank you for playing anyway, and sorry it ruined the controls for you!
