It would be cool if there was new art for when the cage is on in all interactions, boss fights and scenes. It lost the emersion for me otherwise. And a fun side thing would be that only mistress takes it off in some of her encounters.
It would be good to continue to use the glory hole after the 3rd time. The option just disappeared for me. I think that is a fun interaction and you could go way further on multiple attempts.
I know the town is a work in progress but I think it would be cool to make game progression without needing the use of waves. The gameplay loop seems very one dimensional right now.
There is a lot of suggestions saying the same things I would be saying otherwise.
Great work so far I'm looking forward to seeing where you take this game.
