Many players are waiting for the next update, specially the promised online multiplayer.
I am currently working on these features:

• Strategy-mode, 2-16player + online
• Racing mode, 2-16player
• A huge online versus mode for 1-80players
• Single player campaign with levels and bosses, 2-4p coop + online

Lots of work, in combination that I need a full time job on the side so I afford living. So the update will probably take about 2years to complete.

I will make a few small updates in the meantime to keep the game bug-free and running.
