This game was vastly different from any other game I've ever played and I've played my fair share. You are defenseless, but there's nothing really to kill you except for your own mind. The concept behind this game is amazing and the AI for the monster is one of the best I've ever seen. I've read it was supposed to be based on the dev's cat and I can totally see that. It behaves just like a real life cat would, and if you treat it thusly you can generally escape it.
This game was a very well rounded game in my opinion and once I started playing it I couldn't stop until I was finished. I completed the game in two days I think. Not only is it an incredibly unique and interesting idea, the execution was great as well. The visuals, and most importantly the flowers, were stunning and I could tell a lot of them were modelled after real flowers. The story line which you garner from notes left by people before was intriguing and chilling. The behavior of the monster just blew me away. The heartbeat noise alone was enough to get my own heart pounding. I could tell the dev put a TON of effort into thinking out the monster which I must applaud.
At first I disliked the triangulating your position aspect of the map, but after a while I came to like and respect it as an idea. Also I liked that it wasn't as hard as just wandering through the jungle, aimlessly and that you were actually pointed in the right direction gently. The size of the map and the details within the terrain were very well done.
I practically have nothing but praise for this game. I think one of my biggest... dislikes? Was that when you died you were merely sent back to your last save point. So there was really no threat.
Anywho, I would definitely recommend this game.
Probably one of the most memorable games I've ever played.
