Firstly just want to give a big thanks for all the really great feedback recently. :]
Each of the 4 main areas now has a few environmental hazards to contend with. There should also be more randomness to the wall generation.
The way unlocks works has been changed. Hats are unlocked as normal, but gameplay mutators and cheats are now unlocked by doing certain tasks. There's also 10 new achievements, 2 new hats and 1 new gameplay mutator called Ball Busta.
There's 2 new items (Nanomachines, Item Marka), 1 new weapon (Pinga Launcha) and a few minor bits and bobs.
Enjoy. :]
