Thanks for your criticism!
We definitely made things too complex without explaining anything. The clearance level does seem to not matter at times and thats actually where theres an added mechanic technically where the heartbeat-tracker can inform you of something. If the heartbeat spikes, you may find that while they have clearance, they are dealing with trauma and must have that removed. If the heartbeat drops to 0, it's because of a redaction that is needed in their memory.
However, this is basically all but not explained within our tutorial system (which already is quite bad) and totally our fault which then adds further suspicion for you, the player, on whether the confidence level even makes sense. All good things to know and we appreciate you trying it out !
