They really kicked it to max gear for this sequel, the sheer amount of changes and improvements dwarf the previous game by a long shot. The game still does have its hiccups, mainly with performance issues and the occasional glitches, but none that would be too detrimental outside of online play, which definitely has its hiccups currently.

A good update that polishes those errors, and you're looking at a top-notch Platform fighter with a hella creative mechanic and a lovely cast of characters.
