Yeah when he flips into an uncomfortable/inadvisable dimension, the little exclamation point and the arms flailing is the same as Mario's from SPM.
The later stages of SPM with the cloudhopping remind me of this. However, this trumps it in that you can flip in every direction, whereas in SPM you can only flip to the 3rd one and back, and you could only flip in one way. This flips completely around (probably with an L and R button mechanic).
It's very cute. Really cute, AND interesting. Very interesting. :3
