I am the upstream author of this game. I agree it is too difficult. I just released 2.1.2 which is somewhat easier, as the track has been widened. Also, the simulation has been improved. But the nr of obstacles is the same.
I will think about multiple tracks. However, it will be a while before I will get that in. Maybe a detour around the obstacles would work. You could then skip those that are too hard. Skipping one should come with a time penalty. Oh, and lastly: it may be too difficult, but it is not impossible. People were able to set fast times on the leaderboard with 2.1.1 I erased the leaderboard, and can keep an eye on new scores with 2.1.2 Game versions before 2.1.2 will not have their time recorded anymore.
