The Underside - Games

The Underside Logo

The Underside is an exploration based action platformer in the vein of games like Castlevania, Metroid, and Cave Story.

Set on a flat planet, called The World, The Underside begins with the legend of the World’s creation at the hands of a figure known as the Almighty King. When evil overtakes the surface of the world, the Almighty King decides to start anew by flipping the flat World upside down, with the upper side of the World now becoming the neglected Underside, and the blank canvas on the under side of the World now becoming the Overside.

You play a character named Ip, who is thrust from the prosperous world of the Overside into the dark depths the Underside. All the while, the once-benevolent Almighty King is on the verge of destroying his creation. Throughout his adventure, Ip must find his way back to the Overside, and maybe prevent the World from being destroyed while he’s at it.

The game’s world, characters, plot threads, and dialogue are heavily inspired by Earthbound/Mother 2, and are quirky, whimsical, and sometimes a little strange.

The Underside has been under development since early 2005.

    I found how to stop the tutorial crash thing. First, right click the startup icon and select properties. Then go to compatibility and switch it to windows 95 and run the game to the first save point. (level loads may take a long time) After that, switch the compatibility back to the latest version you have, and it should run fine afterwards.

    I would defenitely be interested in supporting a Kickstarter for this. I hope Arthur Lee still checks these comments. This game blew me away when I played it, a true successor to Cave Story. Can someone get in contact with him?

    You can try his twitter (, but even there his last post is from August. Sad as it is, I’d reckon this is vaporware now; if you’re a talented dev, you could take the project over and do a fanmake, or attempt to buy the rights and sell them to someone else. If you can track down Arthur yourself, you might have some luck (he lives in California), but otherwise…I wouldn’t get too optimistic. It’s a sad thing, the death of potential :(
