Thanks for the feedback!
The AI pathing is the real problem, the stupid AI is a product of unity's navmesh failing to properly calculate distances in realtime in narrow corridors/small rooms. Im working on a solution to it, but so far i haven't progressed much. But improved AI is a priority.
Other types of bondage things are planned as well (like blindfolds, gags, etc) but will be getting in, in future updates.
The system for rare spawns is actually in-game, it just spawns "pursuers", which are slightly more stronger than normal opponents, and will take you a lot of effort to make them lose track on you. All of these things will be improved once i can get the new AI working.
Thanks for the feedback, and im glad you enjoyed the demo.
