It is very satisfying to look at this line and curves. But like Dairygold I am also had luck. First three level I am only press W. I like concept of this game :) I don't see limitation, but it is nice to know you learned something new.
thank you for playing! yes its easy to get through in the first three level. the 4 is a little bit longer and not that easy. i see why this takes the fun or the challenge away but i think if the levels all were longer than it would be more of a challenge because then its not luck based anymore
