I got it!. A couple of ideas. If you were in this situation for real, a scary addition would be to have the spider able to shoot webs at you. Ones you can break through if you have a knife and are focused on it, to cut yourself free. This would build a lot of tension if you are trying to escape. To add to this if you were not just looking for card etc to get to different levels...but.. like Aliens :) ... you were trying to rescue say a kid, that's slow, scared and prone to running off if you lose site of them... these two additions would really make this little nightmare a lot more involving. I wonder if longer corridors in a few sections... or a ladder you have to climb to get to the next level...where the Huntsman could ALSO climb it right behind you >:) would also add to the tension. Anyways, that's all from me for now. All the best.
