Polyfauna is an abstract first-person exploration game that is a collaboration between the band Radiohead and designer Universal Everything. In this game, you explore abstract, polygonal worlds based off of Radiohead songs. In each world there is a grey swirl of what seems to be sand, and when chased it expands and slams into the player, transporting them to another world. There are around 8 different worlds, and everything that there is to see in this game can be seen within half an hour. Besides some interactivity in some of the worlds, that's about all there is to this game. It is semi-VR in that you look up and down with your device to look around and move in the game. This game is beautiful, and each world has its own unique features and feels. This game is free, and is definitely worth downloading from the iOS App Store or the Google Play Store.
Bernband is also an abstract first-person exploration game for PC, this time set in a futuristic alien city. Unlike most games of this genre, which have a lonely feel, this game is filled with colorful alien pedestrians which make the game seem crowded like a real city. This game is in the low-resolution style, and really has no goal other than to explore the rather large city. The map is large, and has over 20 locations with a variety of scenes from raves to diners to bathrooms. Hover-cars hurtle by under bridges, and music plays in sprawling squares while teachers teach above. The game tries to replicate a real city with all of its amenities, and its noisiness seems to make a statement about life in the city. This game will really cause you to contemplate its sprawling structures, and is definitely worth a free download from Gamejolt.
