Kid Icarus: Of Myths and Monsters

The Good
This game is a fun action platformer that poses a reasonable difficulty that keeps gameplay enjoyable. Throughout the game, you acquire power-ups that make you formidable against enemies of increasing toughness. Considering the limitations of the original Gameboy, the artwork is great and the music is enjoyable.

The Bad
There's occasional flicker and slowdown problems when there's lots of enemies on screen, but that issue is mostly confined to the final level.

The Bottom Line
This is just a good, enjoyable game. It strikes a good balance between challenge and enjoyment; your errors feel like your errors, not the game being deliberately brutal (e.g. the original Kid Icarus for NES). The level count is a little low, but it makes up the difference with the levels being pretty long. Pick it up if you see it being sold for a reasonable deal.
