In one word: meh.
Good: atmosphere, monsters, art design, spookiness, sense of wonder.
Bad: controls are actually garbage, bugs, crashes, extremely short (about an hour if you're decent at games) the hunger thing wasn't really utilized. It could have been used a mechanic for a sense of urgency instead of scripted.
Pretty upset I purchased this but it was only $5. Which is about all that I can say you should pay. Absolutely not worth $20 and the dlc should be free since the game is so ridiculously short.
