Had a lot of fun... on my second try... Tutorial? Yes please ^^ Very creative take on the theme! The only thing that bothered me a bit was the audio. I think it’s the sound effect when a line disappears? It probably multiplies with multiple lines. It might be worth checking if you can limit it to only play one instance of the sound at a time. But I see it was already mentioned. Also, when I had several connections running, the game froze for a split second about every 5 seconds. But those are just minor things for future polishing! Great job!
