This was rather fun!
The graphics and audio were pretty good.
The start of this game is however the actual gameplay. It was really scary, but I must admit, I never got that inert feeling of danger. I would whish the monster was a little more erratic, or a little more sudden in her movements. Much like a spider. Perhaps she could have crawled on the roof. It becomes a little repetitive towards the end.
But the experience was overall good. The mechanics worked well, the game was somewhat guided so that you do not get stuck.
Good work!
