*DISCLAIMER: Discard your expectations. It's barely a game. It's more like an interactive wallpaper, really. XD
An ambient, very simple game* with pseudo-puzzle elements, something you can leave open on a second monitor while you work.
Experience this peaceful world through the eyes of a sentient pillowcase. Navigate dreamscapes and curious events best experienced, but not dwelt upon too much. After all, a dream is just a dream, right?
Click on objects to interact with them, press Z to zoom in/out
Alter the dreamscape through interaction chains
Unlock more dreamscapes by opening portals
But most of all, just enjoy. Even if it makes very little sense. ^_^
