Dragon's Lair is much better known in its incarnations for other platforms as an FMV game with only slight amounts of control over the player's action. The NES version is more of a traditional platformer, but very smooth animation for the era and funny-looking characters inspired by the cartoon graphics of the other versions - this includes the final boss, who isn't seen very much in this run thanks to abuse of the game mechanics.

This TAS by ktwo is done on the slower USA release of the game, since the differences in execution for some of the levels are different than on the Japan release. You can watch the TAS of the Japanese release of the game here.
