Very enjoyable game. Very impressive !
Really appreciated the overall Aesthetic, it all fits nicely together. (Maybe the chibi in the tying up instructions poster is the one thing that tonally stands out)
Having instructions be part of the decor is a really nice touch. A bit overwhelming since they all are available at once rather than progressively introduced. I was a bit confused in regards to the numbers displayed next to the restraint type (only figured out what they mean and that you have to interrupt the binding to have lower levels by reading other reviews) and where to click to do the purple binding.
The one thing lacking is probably feedback to the player after their actions.
Maybe another idea to go further would be to have lighter capture elements come into play in the middle of determining if the agent is a spy or not.
