VVVVVV is an indie puzzle platformer that costs $4.99.
The gameplay consists of 2D platforming but with a twist where there is no jump button, instead the player is tasked with changing the gravity in the level in order to have the character fall in the opposite direction to the other side of the stage. It is through this gravity mechanic that the player can traverse each level trying to reach the end.
Pro Throwback to Atari/C64 games while playing like a modern game
VVVVVV is very reminiscent of a game one would find for the Atari or Commodore 64 in that the graphics are simple, but the gameplay is anything but as it plays like nothing one would have found back then. It is fast paced and very precise, also extremely tough.
Pro Use gravity to solve puzzles
The main mechanic in the game is that the player can switch the gravity in any level allowing the character to flip from the bottom of the screen to the top. This is used in an ingenious way in order to solve puzzles and avoid hazards throughout each level.
