Deducktion

You are a boy named Mark who has been trapped inside his house due to the zombie apocalypse. In an effort to preserve mankind's last hope, you have sent your turtle out into the streets to retrieve the one item that can save the world: the wand of duck's bane, the key to performing the ritual of deducktion.

Deducktion is a standard platformer, but with a twist: instead of stomping enemies, you have to hit them from beneath. Oh, and you can retreat into your shell, which is very useful. And jump twice. So, yes. There is nothing generic about this platformer.
