Great idea, but your left wanting for more.
For a start. the controls are a little clunky and hard to get used too, it'll take a few minutes before you get the hang of them, but they do their job, just not as well as they could have. Trying to tinker with objects can be a problem at first, especially if your trying to do it fast so noone spots you, i had to try a couple of times before i faced in the right direction to destroy a present on a fire.
The games AI is fairly good, when scared, the bears will hide and barricade the doors to prevent you from entering the room, when not scared, they will also wander around searching for you, unfortunately its all to easy to hide, so its rare they'll find you.
The game can be slightly depressing however, pulling off some of the harshest attacks you'll probably see against a teddy bear in your life. Such as smashing a bears head in until it goes flat, and stabbing it in the stomach with a sword. Or alternatively, if you scare them enough, they'll commit suicide with whatever weapon they have in their hands. Unfortunately you can't do straight out killing, the game requires you to be close to the bear to actually kill it, so you can't sit in a bush and shoot a bear repeadtedly in the head and expect it to die. Although annoying, it does allow for some cool cutscenes. Scaring also only works as close range.
The graphics remind me of a 2004 game or so, sort of a high end PS2 game or a PC game of the time, nothing impressive, it does its job and thats it.
Probably the biggest problem, is the fact that all the missions are very similar, basically nearly all of them involve scaring the bears to death (literally, you can make a bears head implode if he gets to scared) and plotting their demises through evil schemes such as sabotaging a barbecue, then when someone comes to fix it, shoving their face into the flames. A few missions have special requirements, such as friendly challenges force the player not to attack anyone, even if they attack him, meaning the only way to win is to scare the bears to death.
Really the game has little to offer, apart from humouress moments and some heartless teddy bear killing cutscenes. I would spend your money elsewhere, this game may provide enjoyment for a few minutes, but you'll soon be left wanting more.
