Glad you're enjoying it! For the lag, were you playing the web version or one of the download versions? I'll try and patch out lag if I can, just trying to gather more info to narrow down the problem :)
Thanks for the info! Makes sense. Godot's web exports sometimes struggle. I'll see what performance improvements I can make. In the meantime, the download versions usually run better if you want to try the one for your OS of choice and see if that helps!
