This is a complete solve for Dragon's Lair. It may spoil some of the fun of discovering the moves on your own.
All moves are in brackets.
The rooms are grouped by level. When your game ends, you are sent back to the first room on whatever level you've reached. The order of the rooms will be randomly chosen within a level. Certain rooms will appear backwards, and all left and right moves will be reversed, but NOT up, down or sword. I learned these moves on my own.
