Last version 0.42_beta, very raw. Why not aviable old map? 0.4 is prototype of multiplayer. So it contain only simple track for chalenge. 0.42 have also prototype of the track constructor. You can download old version. Press "Install game", and next "download direct". This is zipped old 0.3 version.
ever since the newest update it lost all of its rawness. even the controls have been messed with, i used to be able to do 360's through skills, now when i press the same combination of buttons to get the bike to rotate it completely fails. theyve dumbed it down for anyone to play. it sucks now.
