Maybe it's because I've been playing too many hypercasual games but I didn't find it fun. Everything about it was very slow, even level transitions and death animations. I got the impression whoever made them really liked them and wanted to make sure we looked at them a lot. I understand that if it was faster then switching directions would be even more frustrating to get right so I guess it's just a game for someone with a lot of patience.
It felt a bit nicer when I gained the power up to draw 3 lanes at once. But even if you have patience I don't think there is any incentive to go back and roll over 100% of the land, I just wanted it to be over. There are some nice ideas, I think maybe they would work well in a cleverly designed multiplayer game where you take over the land of an opponent or something. Well you completed a game so well done :)
