The Worm enemy has an unused set of walking sprites, with less exaggerated movements compared to what the final game uses. They can be found in the file Worm_Walk_49.jpg, while the alpha channel is Worm_Walk_49_a.jpg, both located insde of the folder Data\IC_Character\Worm:
Throughout the game's data are several reference pictures for some of the game's screens:
The directory Data\IC_Play\Score_Num, which contains the number sprites seen in the gameplay and bonus stages, also contains graphics from a removed combo system. Note that the latter graphic seems to be a leftover from Caveman Rock, also developed by CyberPlanet Interactive.
The root Data directory also contains some unused graphics, as listed below:
number_(12,18).bmp is an unused graphic for numbers. The file is dated December 27, 2004, much older than everything else in the data, and seems to be a leftover from Moontra Kid: The Ghost City.
Found at offset 0xB3970 of the game's executable are leftover text strings from Deep Hunter, a previous game by CyberPlanet Interactive:
