Music Catch. Catch the colorful shapes that appear when the music plays! The more shapes you collect, the more points you get. Yellow shapes give you a bonus and multiply your points, but watch out for red shapes!
EDIT: Thank you all very much for your comments and responses! Regarding the music for the game, it was composed by Isaac Shepard and is called "Before Dawn" from his "Swept Away" album.
UPDATE: You can now listen to music and download sheet music at www.isaacshepard.com. Also, the "Swept Away" album is now available on amazon.com.
ANOTHER UPDATE: There is now a download-version of Music Catch that includes lots more songs and allows you to play any MP3 you have on your computer! Download it at: www.reflexive.com/MusicCa tch.html
