there's an invertDisplay function for the display, if you can find a version of the library that works on ESP8266 and you pipe in some lines of code... not the point now. The concept is inspired by stranger things, you have to get through a world and run into obstacles. You can only get through certain worlds by changing to the upside-down world (meaning invertDisplay) but there is that creature that closes in on you when you move, so you can't stay long on the other side.
