a few u might like to try are arcano, elf logic, falldown, oh! my godness (really gud game, but quite big), gpgames, kof91 (make sure u get this one!), andyman and gloop.
Thats just a few to get u going. theres sum classics out there, just hav a look around a few sites
Fire nFire is cool, a little simple but still a bit addictive, Connect4 is a little easy, Puzzel mix is a great coolection of puzzle games but I kinda wish it was a little faster and had a music option.
Yes it is. It's a very big tetris clone (taking up 30mb) but the backgrounds are in an anime/manga style, there's a story mode (although in Korean) and lots of music. I think someone made a compressed version of the game without the sound effects and music which makes the file a lot smaller.
