It's an interesting implementation of the idea of connecting dots. I have to say that it loses its fun rather quickly tho. It could also be nice to have some feedback when you try to create a new line but you can't since you reached the max amount of lines in game, at some points, I just tried to create lines and couldn't tell why they weren't showing up (of course it is because I already had 5, but didn't get feedback besides the line not showing up)
