Oh I will have to look at these textures, that shouldn't happen. By any chance, was your browser zoomed in or out? Thank you for the feedback.
Truth be told, Asheraryam had implemented player vs player from the beginning (so we could test the gameplay before there was an AI) but it was buggy and was disabled before we submitted the game. You'll be happy to know that he plans to fix it and re-enable it after the jam ends.

I had this trouble in my last project too: the pixel-problem is caused by the windows setting "screen scale". Using a laptop Windows sets up 150% scale. Maybe you should use the "Stretch"-Method in Godot Project Settings to solve the problem. (At least this is what I did and it solved the dilemma) 👍
