Considering most cheap survival horror video-games involve an insane asylum or hell, this seems...cheap.
And now a list of observations:
1. Death cannot occur in this setting, which is fine, but it takes away from the whole 'survival' aspect
2. The whole insane asylum thing seems misused
3. The setting of an asylum in hell seems redundant and could easily do away with either aspect
4. This feels like an ending to something
5. I don't see a hook. Perhaps the asylum or hell is supposed to be an exploration of the characters' inner guilt? Actually that would be called 'silent hill RP'
