I want to like this game.....but compared to so many other sidescrollers, it isn't very good. bad gameplay, bad graphics, bad art, and a story that doesnt grab your attention. VVVVVV probably isn't worth your time or money.
Gameplay- They took a simple control scheme and made it simpler (simpler? more simpler? Whatever, you know what I mean). You can't jump, instead you just reverse gravity to fall up and down. This is supposed to make it difficult, but it isn't as hard as you will be told, and forgiving checkpoints make it even easier. Oh, and exploring the open is a huge pain in the ♥♥♥, chances are you will get lost.
Graphics- More retro than a Megaman game. It's indie pixels, which I would usually like if they added a good artstyle to it...they didn't. VVVVVV's artstyle is a headache inducing mesh of rainbow colors that don't really match. If you don't like bright colors and fast moving shapes, don't buy this game.
Sound- So this is a part of the game i actually liked. The music was also retro like Megaman, but it was also really catchy like Megaman. Probably the games only good part.
Story and Replayability- I actually lost interest in the story after the first hour, if anything interesting happened please tell me because I just skipped over all the dialogue after that (probably not a good thing because I'm reviewing this game but hey, it can't be that good if I got bored of it right?). The game itself could easilly be beaten in a day, unless you get stuck on one part for a REALLLLLY long time. Oh, there is a level editor, but while would you play player-edited levels if the developer made levels wern't that good to begin with?
Conclusion- So yeah, I don't like this game, pretty crap if you ask me. the music was kinda catchy, but the gameplay was crap, the graphics and art were crap, and the story might be crap. I've heard of a few people who do like this game though, so this game might be better than I'm telling you. But I'll never recommend it.
