Wani Wani World , a modified version of The Berlin Wall, is based on Space Panic from 1980. Two small dinosaurs, Charlie and Smiley, with large hammers, navigate through multiple screens filled with enemies. They use their hammers to create holes in the ground, wait for enemies to fall in, and then attack them head-on, turning them into items and food.
The game is divided into five worlds, each with several screens and a final boss at the end. There's also a minigame between worlds where players can earn bonus items. Wani Wani World can be played alone or in two-player co-op.
