EPIC PUZZLE!
As far as the health upgrades go, this game is a keep going game like god of war while warrior within was an open world. If you don't find something, you're screwed. Whether or not you find the upgrades is chance because most of the time what direction you have to go and the secret direction are indistinguishable, so when you realize you're going the wrong way from the secret you can no longer go back. The most irritating part is the epic puzzle factor. Puzzles can be solved if you can look at it and think or it's in a small room, but when you have to move a giant statue across a massive conveyor belt to correspond to a certain spot to turn and have it push back to exactly the right spot when you can't see the whole room at once is hard. One of newest aspects of this game is the Dark Prince. Although you look awesome, gameplay isn't actually much different. Yes you have a chain that link to things far away and it's a permenant secondary weapon, but the only really bad difference is the timed factor of the puzzles. The Dark Prince's only way to get health is with sand pick ups and his health constantly depletes. Timed puzzles are irritating. Anyway, on the whole( even though most of this thing has been negative) the game is overrall fun despite it's setbacks. 9 out of 10.
