Wicked Surfing is a cancelled sport game that was in development in 1999 / 2000 by RUNANDGUN! / Cave Barn and it would have been published by Interplay for the GameBoy Color. As we can read from a short preview on IGN, in the game you would have been able to use 5 playable characters to do various surf-tricks in 2 different modes: Thrash Mode (timed competition for points) and Contest Mode (tournament against other surfers). The team that was working on Wicked Surfing was small (1 programmer, 1 artist and 1 musician), but the graphic was really good for a GameBoy Color, with an isometric view and a nice palette. Sadly Interplay was in some economic issues at the time (in 2001 it was acquired by Titus Interactive) and they decided to never pay Runandgun! to finish the game, even if it was almost complete.
Thanks a lot to Jeremy for his help to preserve more screens of their lost game!
