Summary
A true classic.
The Good
This game reminds me a very old Atari game by the name of Atlantis, but since it's been ages since I played it, I might be wrong.
Basically the game is very addictive and challenging, with hours of gameplay -- until it finally gets to you, then you shelf it, and once every now and then you rediscover it and relive the classic.
The Bad
The graphics are very amateur (even for a CGA game), and the game is too repetitive and after a while it simply annoys you.
The Bottom Line
A true classic, one of those games you simply have to experience.
