Quite simply: the best puzzle game ever made.
...
I guess I have to eat those words now.
Lumines is, by far, the best PSP game to date. With is highly addictive, yet simple gameplay, Lumines soares to the top of the PSP line up. Even though the concept is simple (line up the same color of blocks to make a square, and build on it for combos), the game is actually hard. There is a strategy to building the blocks up to make them disappear. If you get caught up with too many extra blocks, and they fill up the screen, it's bye-bye to you! Also, the different levels are called skins, which are just different songs. With every move you make, every block you lay, and press of a button, it makes a certain sound/part of the music start to play. Once you complete the song, you move on to the next skin (or song). Every skin you complete, you unlock that song and can play on it whenever you wish. So it's like a music puzzle game. Even better! And most of the music is actually pretty good.
The different modes of gameplay are great too. From single player, to challenges, to versus, there are tons of ways you can enjoy Lumines.
The sound in the game is amazing. Very vibrant and clear. Music is actually good as well.
The graphics in the game are really good...for a puzzle game. Everything moves very smoothly. The backgrounds are very animated and fluid. Definately easy on the eyes.
Overall:
I would say that if you love puzzle games, happen to have a PSP, and love music, then you need this game. It's not that you should get it, it's that you need it. To date, it is still my favorite PSP game.
