If you ask me, one of the core aspects of any game are the mechanics. I have seen many games with absolutely wonderful ideas that simply were not able to pull it off successfully in terms of the controls and gameplay. Many Wii and Kinect games, for example, are ultimately hindered by their presence of motion controls in games that could really shine if they were used properly.
For this game in particular, the usage of looking left and right repeatedly simply isn't a good mechanic for ascending. It makes moving for long stretches in one direction a very difficult prospect, as well as making descending and moving upwards while staying to one side extremely difficult.
In order for a difficult game to be fun, the controls cannot be what causes most of the difficulty. The difficult games that you mentioned, Super Meat Boy and Dark Souls, had very tight and well put together control schemes. This meant that the player was being punished for their lack of skill, not for their inability to work with a broken system. Because of this, I have to say that this game fails right out of the gate.
