The Great Cake Escape

From BoardGameGeek:

In The Great Cake Escape, players take turns pushing tools in between the layers of a three-layer, 3D cake, tools like shovels, chainsaws, and even dynamite! As you try to hide your pieces, you'll push your opponents pieces out - or at least make them visible enough to get caught by the guards. The more you hide, the higher you score! -description from the publisher
