Played this for such a long time, made a "late-surger" build focusing primarily on stamina. Super fun and I felt very maternal for the snails especially the doped-up/goopy ones. I also had performance issues but I'll try downloading the windows build and see if that helps!

Happy to hear that you were engaged with the game ! I'm sorry to hear that you encountered performance issues though, definitely give the Native Windows PC build a try, but otherwise I'd be very interested in getting some information about your configuration and browser to debug this and learn more about Godot optimization !
