Summary
Probably the game I spent most time with of all games!
The Good
The game contains much levels, which have a slowly upgoing difficulty, but never is too easy that you get bored of it. All levels are replayable at any time which makes it fun to play a level again sometimes when you want.
The graphics were for the time it got released really good and especially very smooth. Also the game engine was very stable and everything always went the same way so you could calculate to solve puzzles.
Me and my family spent at least 500 hours on playing this game, from which 200 hours with levels which we didn't save yet (it counts the time you spend on not-saved-levels) but i'm pretty sure we spend at least as much time at replaying levels. With some friends after school, take turns on saving a level, that was fun!
The Bad
I liked allmost all of this game except maybe that some levels might be slightly to difficult or even close to impossible.
The Bottom Line
One of the best, most addictive and best designed puzzlegame of the past century. Fun for hours, for kids and adults. Everything a game should have is inside. The concept is taken from Boulderdash - but it's a damn good clone, so who cares!
