TIme wasting game VVVVVV

Info
Another nice, time wasting, addictive game, which you won't stop playing.
Unlike most platforming games, in VVVVVV the player is not able to jump, but instead can reverse the direction of gravity when standing on a surface, causing Captain Viridian to either fall upwards or downwards. The player utilizes this mechanic to traverse the game's environment and avoid various hazards, including stationary spikes and moving enemies. Later areas introduce new mechanics such as moving floors or rooms which, upon touching one edge of the screen, cause the player character to appear on the other side. VVVVVV contains eight main levels situated inside a larger open world for the player to explore. Due to its high level of difficulty, the game world contains many checkpoints, which the player's character is reset to upon death.
My review
This is what I call a game because it's simple, it has innovative idea and when you are bored - it's number one activity you should do. Seriously one of the best games I played with one of the best soundtracks ever made.
