Mole Mania

The Good
The biggest draw of this game is that many of the puzzles have multiple solutions, and not just the "multiple variants of a single solution" kind. In this game, it is perfectly possible to finish a puzzle, and have a piece of tubing, or a barrel (or even half the field in a couple puzzles) left untouched. While this may not sound like much, it makes the puzzles feel much more natural, as opposed to the "every piece used, perfect solution plotted, possible to complete in exactly N moves" of basically every single other puzzle game ever created.

The innovation of having surface and underground levels works, by the way. You must keep an eye on both levels when planning a solution, and most of the puzzles would be much more boring without that second level.

Finally, you are able to skip around puzzles that you get stuck on, by either using an item, or by going to one of the other 7 levels. Nice touch.

The Bad
First, the bonus sections. (In these, you run around trying to avoid a farmer while dropping cabbages down holes. There is a time limit.) These seemed quite out of place, considering the puzzle-oriented nature of the game. More importantly, they are significantly more difficult than the rest of the game, turning them from what could have been a welcome diversion to an annoyance. While they do not need to be completed to finish the game, they are needed for a 100% rating.

Somewhat less of an issue is the placement of underground enemies in the later levels. As you can't actually see underground at the start of each puzzle, there is a possibility of unfairly running into an enemy you couldn't see. While this just requires a quick restart of the puzzle, it is still irritating.

The Bottom Line
If you like puzzle games, but want something a bit different, this is the game for you. There's plenty of puzzles, and the concept is interesting.
