8-Bit Night is a pretty clever puzzle platformer with a fresh swapping mechanic that allows you to turn the world around you vertically and horizontally. In the game you control 2 guys at once (the main character and his phantom counterpart) with the goal to collect all golden pixels on the screen. In order to solve the puzzles you have to make use of the swap button to exchange positions. Beside the trailer consider also to check out this 4 min video that showcases the first few levels of the game.
Owlboy is a great platformer with fantastic pixel art where you control Owlboy in a Steampunkey world. I have just tried the recently released demo and it’s really good stuff. Check it out! You can also watch this 1 hour playthrough of the demo to see what the game has to offer.
