Peggle Clone is based on the PC game Peggle (TM) by PopCap Games.

Changes:

complete rewrite in toolchain (from jiggy)
Much better collision reponce ( now the ball balances on pegs, rather than falling through them)
A lot less lag: runs smoother, and supports way more pegs
Fullscreen (in the right orientation this time)
Many other improvments.
