I've just finished playing Shadows Shelter and though most of it didn't get too scary, there were some eek! moments. Really loved playing this one. This music was not the same as the video, that metal stuff was only in the beginning, the rest was unusual ominous but not freaking out loud and stressful.
The gameplay was all HOG, no puzzles at all really. You won't need a walkthrough, the map combined with hint will always get you through. The house has endless rooms!! I thought the game was going to go on forever. But took me about 3.5 hours, no interruptions.
Verdict - much milder than the video, but still scary at moments, with the creepiest being in the teacher's classroom, for my books. One of those games you don't want to leave, which is why I'm still up at 6.30am!!
Bed for this game addict! Cheers!
