PAULNOJUSTPAUL  I think I still have my registration letter (yes, letter!) from this app's shareware days. This was a titan in its day, IMHO, and is still a lot of fun today. They get about a million bonus points in my book for open sourcing this one too.

Andrew Welch and Ambrosia are an amazingly cool, talented bunch of people, and they to this day maintain that original spirit and do really great titles.

I'd also recommend checking out Mars Rising and Deimos Rising, written by the very talented Dave Wareing. They give arcade games like Xevious, and Raiden a seriously good run for their money.

MICHAEL  Oh, sweet! I am a huge Ambrosia fan, and how can I forget the game that put Ambrosia on the maps! Just like the original but with updated features, such as network play and access to a WORLDWIDE high score list! Definitely a must-have for any nostalgic Mac gamer!

ANONYMOUS  Could use a revamp on the graphics, but otherwise for free, this is a great game!

ANONYMOUS  Very challenging! I played the old one too, and

this one's better.

JASON  Thank god for a fun, free game for Mac OS X! I remember when I use to play this on my old Macintosh IIci at 33MHz. It was great then, and is just as great now.
