its not out yet, but when it comes out, I am so getting it, this game looks HUGE and more adictive then Lumines, plus, I am about the biggest MM freak here.
Rented it played it for a couple of hours and so far it's a fun addicting game with lots of levels, It's pretty basic but has lots variations to it lots more than I was expecting. It can get really tuff to play but really none of the levels are really all that difficult just need to have your timing right. I'll also add this is a pretty good game to get good use out of the joy stick so if have a little control problems with the PSP joy stick a little time with this game and you'll be pro. Don't want to say too much as I haven't had a ton of play time with the game and really only done the first 2 worlds but DEF worth a rent and maybe a good game to buy that will hold you out until games like GTA come out next month.
