Heyo! I had a lot of fun with this game even if I also had issues with it. The generation of the maps is fine, though I do feel some more furniture would help with the layout of the map.
I started the game confused. Really confused.
I had no idea how to navigate the map (actually I didn't know there was one at first) and found myself needing to check it while being chased just to not get trapped in a room. Hiding from the Widow is difficult due to the way she searches for the player after losing sight of them, often cheaply having her bolt towards you and look behind the exact piece of furniture.
The doors are another thing, as some have stated they're more than a little difficult to close while running away, and doing so is the best way to have her lose sight of you. Making the doors have no player collision while closing would make it a lot less finicky.
I think the best course of action is to fully swap the unlocking system with an achievement system.
I feel like unlocking the different items over buying them with money is the best bet due to the simple gameplay loop. The stamina + health upgrade doesn't feel needed and, in the case of the stamina upgrade, trivializes the game very quickly.
The Key glow/sound upgrade should be default with the game, the key sense thing is nice, but only because the maps should be a lot smaller in size. Having the AI stay in your general location does keep the player engaged, but due to how large the maps become and how little the map generates circular sections it feels really cheap and frustrating.
The outfits could be unlocked through doing certain things like beating a level in an amount of time, beating a level for the first time, beating a level without using too many items, etc.
Keeping the NSFW animations being a pretty substantial time window is also not that fun.
In summary, I'd suggest making the maps smaller and have less dead ends (at least dead end hallways and such), swapping the shop with an achievement system to help keep the gameplay loop fresh each run instead of having the player redo the same thing over and over, and tweaking the Widow to be less cheap in their ways of finding you.
All in all, not a bad game, but it's got some very frustrating mechanics that could be swapped for more fun and dynamic ones.
Keep up the good work and all that jazz!
