That's weird little game (in a good way)
I wouldn't say that controlling the lines curve is intuitive... but trying to figure out how the line react to your inputs and so how use it to go to the next line was fun. I think if the player could have more intuitive and direct contol on the line it would not have been as interesting.
There is no so much replay value and depth to it but I enjoyed playing it.
Congratulations for finishing the game during the jam.
