My first attempt. Actually my second.
I love this game. But sometimes it's so easy to get trapped. Besides just killing the enemies and using the items to help you, it is a good idea to pick up items even if you don't want to use them because most of them give you points. All except the candle stick and comb i'm pretty sure.
And for a refresher course.
The Grail = Energizes the knight (probably the most useful item)
The Crown = Freezes guardians/enemies for a few seconds (it has come in handy when you get energized and they are close by)
The Necklace = Speeds up knight for a few seconds (also very useful for offense and defense, can get you out of trouble)
The Lantern = Doubles knights energy (i assume it makes you energized longer, haven't really noticed and i rarely use it)
The Key = Let's knight move through gate or wall (also very useful on offense and defense, don't know how many times i get trapped and wish i had a key)
The Ring = Moves knight to a random location in maze (what a crappy item, hasn't helped me yet, last time i used it, it transported me 2 inches away)
Coins = Adds 500 points to score (grab these every time if possible)
Candlestick = Grants you and extra life (hell ya)
Comb = Cuts your score in half (try your hardest never to grab this
