Proto:Wacky Wheels/Wacky Wheels 1.0

Version 1.0 of Wacky Wheels was a review copy sent to a UK magazine, likely this one. It's a shareware version (i.e., much of the registered game is not available to play) but appears to be feature complete in terms of gameplay.

Sprite Modifications
Several of the characters (Sultan the Camel, Peggles the Pelican, Razer the Shark, and Ringo the Raccoon) had dark, cartoonish outlines which were removed for the final.

Multiplayer Taunts
The review copy featured a more useful set of Giggle the Demon "taunts" which actually served to communicate information to the other player, rather than simply trash-talking them.

Command Line Parameter
If launched with the command line parameter, the game will display "Trace on" on startup. It's not otherwise clear what this does.
