Sprites--
CatBowza has remastered animations and talk sprites.
BF and GF have the Smooth sprites from Gamebanana.

Hell Mode--
A new difficulty, Hell Mode has been added to the Hotel Hassle week. Basically it's an overcharted-to-hell-and-back version (yes, it's clearable)

New Mechanic--
For the Skatepark Skirmish week, there is a new type of note in the editor caled the 'Sk8 Note' (not fully implemented but it works)
It is a "must-hit" note, meaning that if you miss it, you immediately die.
An example of this note is in Hellish Hassle (Hotel Hassle Hell Mode)
