This video game stars Boomer (Asmik-kun in the Japanese version), a pink dinosaur, coursing through maze-like levels through a large tower. Boomer traps enemies by digging holes and letting the enemy fall in them. Boomer can also dig out items and keys needed to complete the levels. Passwords are revealed before and after every boss level, every eight levels.
In the game, Asmik-kun has to build a "road" from the entrance to the exit in each level. An enemy has come to kidnap the children on a certain world and the "roads" are intended for the children to be rescued and escorted safely back home.
