Okay, the first thing I noticed is the continues. You should NOT have continues imo. You should just lose some items that aren't equipped and potions if you die, having 3 continues made it near impossible for me, and the bosses are too hard imo. 3/5 because of this, but otherwise it's a pretty cool game.
It's good, but the gold that drops from the air would be much better if it didn't come towards your magnet, then you can just leave the game on all day and you'll end up with a million. Good idea though.
