I'm working on 0.2 version, it will be available in a  week or so.
Here is a (not official, lol) list of improvements and features:

• new cars (panda, super quad, maybe more...)
• new surfaces textures
• better car lights
• general bugs correction (respawn, track creation and something more)
• improvements in cars AI (i.e. no more stupid self-killing jumps :D )
• big improvements in car controls; the game was really too hard and frustrating to play.
• new main menù layout and graphic
• player preferences (laps, number and type of opponents,  kmh/mph, player name)
• player favorite tracks list
• best lap and total race time saving for every track with a top 10

See you soon! :)
