Nice visuals. Some reflections over the jelly & sparkly particles inside it would be awesome. Darker background might help.
Control is too tight. The time between auto switching direction is too little. If the time difference would decrease & get faster over time starting from a easy slow switch, it would be much easier & won't even need a tutorial.
Obstacles look attractive & inviting. Make them menacing by changing color/ change shape. I'd prefer electro music without trumpets.
Good job. :)
