It's so terrible.
The gameplay is just awful: our dear hero has reflexes so bad that you end up crying already in the first screen. Every trap in the game seems to be there to get you, and you start to imagine the whole game is whipped up from all the bugs they may have had in other Dragon's Lair games.
The graphics and the sounds do nothing but scare the poor player, if he/she decides to play this in the evening. It's just so awful, clumsy and eerie for the eye and the ear.
This game has pretty much no value to me, except probably for being the less-than-proud owner of probably one of the most hideous titles on NES.
