Worth all the time put into it.
The game is not too long, and is not of too high of difficulty yet it is very addicting. I couldn't put it down once I started. Although the story like all old games lack in plot compared to today's standards, but it is still one of the best games for the Game Boy.
The game takes place in a fantasy world named Angel land. Just based on the fun game style players should be addicted to it at once.
The lack of color doesn't effect the game play at all, it was so good it almost seemed like that there was color anyways.
All in all, this is a very good game with very little flaws, a must get for Game Boy.
