Alphablocks by IceDaddy is an educational program for pre-schoolers to get learning letter sounds.

Alphablocks v1.0

Release notes:

This is now version 2. It is exactly the same functionally as before but it has been upgraded to use viDSnips 2; so the sound is vastly improved, the video playback is more robust and the game size is much smaller (about half what it was before).
