VVVVVV is a retro styled 2D platformer by Terry Cavanagh, creator of dozens of free games. You play as the fearless leader of a team of dimension exploring scientists who inadvertently crash, and are separated. The game involves exploring the strange world you've found yourself in, and reuniting your friends. VVVVVV explores one simple game mechanic: you cannot jump - instead, you reverse your own gravity at the press of a button. The game focuses on playing with this mechanic in a variety of interesting ways. The game is designed not to artificially gate your progress. In VVVVVV there are no locks, no power-ups, no switches, nothing to stop you progressing except the challenges themselves.

9/10 - Agree Disagree

You need a lot of courage to create in 2010 a game with a ao retro DOS-like look! The creators of VVVVVV do it and we can just aplause them for this great game! Tricky and sometimes extremly hard if you want to complete it 100%, it's also very addictive! But be carefull, after some hours playing it you could want to trhow your PC in the wall! Everything is done to stress you up - music, noises and a lot of scenary moving around...
