Catrap

The gameplay is very similar to Mole Mole , and is best described as a mix between Boulder Dash and Soko-Ban .

The goal is to clear each screen of bad guys, in 100 increasingly difficult rounds.

You can punch a bad guy by walking onto it from the left or right.

You can't attack from above or below, but you can stand on top of a monster, or underneath a monster.

Other elements to make the game more interesting are loose ground which you can stand on or dig through, ladders to climb and boulders you can push around.

You can choose to play each round as a boy or a girl, but this doesn't affect gameplay, only the background music.

In some rounds, both the boy and the girl are present at the same time.

You can then switch between them with select-button, using both of them in clever ways to solve the rounds.

During the game, you can rewind to undo certain moves.

You can play the rounds in any order, so you can skip to more difficult ones and solve them at a later time.

There is a round editor to create your own puzzles, but these self made rounds can't be saved.

Catrap for Game Boy is currently worth €49.68 loose, €160.00 complete in box, and €251.82 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Catrap has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Catrap, loose is €49.68 and CIB is €160.00 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
