Love it! That mode 7 garden path view is absolutely spectacular, well worth the many hours I'm sure it took to figure out the registers! Would play a lot more when there is a lot more!
-Didn't have a problem with the jump personally using a snes pad. I liked the physics, had a nice floaty feel.
-Not that keen on a shoulder button doing the heavy lifting for anything however, would have preferred a face button. But maybe that's just me.
