The Lost Vikings wasn't the first game to let you swap between characters to solve puzzles, but as would quickly become a trademark of the soon to be Blizzard Entertainment, they took an existing concept, and polished it up to look better and play better. This was one of the earliest examples that would start to build their reputation for quality design. The levels are varied, the puzzles are mostly well done, and the audiovisuals round it all off nicely with a cartoonish and whimsical feel.
