From the review:
"It's a credit to the game's development that even though the graphics are basic, I still felt a strange amount of endearment to the main protagonist, Veridian. He reminded me slightly of Sackboy from Little Big Planet while also harking back to my memories of the Dizzy games back in the 1980s. Constantly smiling away, nothing seems to get Veridian down despite being faced with many, many perils. His mission? To save his crewmates who have been scattered across a strange dimension after their spaceship crash lands. VVVVVV is a 2d platformer at heart with each of the levels not being overly long to complete, assuming you know what you're doing. It sounds simple, it isn't. Veridian only has one ability at his disposal: the ability to invert gravity. It might not sound like much but it makes for some very intriguing puzzles."
