nice graphics ... nothing new
in short words : the game play is fun ... the graphics R great ... but still super mario cart classic on s Nintendo is more fun !
I think you still can do to the game much more...
U'd done well on programming, art, menu ... all that stuff ...
but as a player, I want something new, a weapon, a new upgrade... funny characters, there is much you may add to make the game feel different.
still, its a fun game to play ... good work
