When playing the AstroPop game in the Xbox Live Arcade demo section, you
can obtain unlimited play as the default "unlocked" character. When you
reach level 3, you will be asked if you want to continue or purchase the
game. Continue normally or press [Back].
Both choices will let you
continue playing. However, when you come to the next "demo checkpoint",
which should be the beginning or end of level 7, you will get this
question again. Normally, you are only permitted to purchase the game.
However, if you press [Back], you will be permitted to continue playing
(up to 10,000,000+ points and at least level 46).
You can play as far as
you are capable and attain much higher scores. You will also get to see
the new colored blocks that are introduced, etc. Once you "die", you
will get a final statistical screen like any other demo session, and can
do it all over again.
