Pros: Fun top-down puzzler that has the player navigating two planes, the surface, and the underground, as you tunnel down and pop out from the other, to solve puzzles, push and throw big ass bowling balls into holes, nab cabbages, and open doors. Really fun stages, really polished design, and plenty of personality and charming characters (Grandpa mole is a favorite of mine). Gotta mention the art/character design, which was made by Yoichi Kotabe, the man behind the 2D art of Mario, as well as Pikachu (also I believe this game was backed by Miyamoto himself, so there's a lot of Nintendo vibes here). Plays great on Super Game Boy as well!

Cons: There's not a whole lot of cons here, other than, and this may not even qualify as a con, but that this is a game that would've benefitted greatly from two screens, like, if it were on a DS. It'd be useful to always see both the underground and surface at the same time. As is, you can always pop your head up to check whats happening on the surface without fully committing, but, if you were always seeing what was up there, it could help with some puzzles quite a bit, like moving enemies or obstacles. Eh, not really a complaint so much as a desire to get a DS version that we never got...

What it means to me: Pretty sure I saw this game featured in Nintendo Power, didn't think much of it at the time, but many years later I saw it used at a Gamestop, gave it a purchase, and gave it a play, and kinda loved it. It's a great game!
