It definitely needs a tutorial, by the time you figure it out, the game is too hard to play it.

this is slow and boring

There are no direction/tutorial and I'm not familiar with any games like this. The art is basically a few shape and colors and you have no background music.

What are we supposed to be doing here? Some instructions would be helpful. I've never heard of a "lines" game, let alone a classic one.

I don't understand this
