This is honestly one of most interesting erotic games i have played, i have read the comments and even if you do not continue this game in specific i do hope you try the "exploring" aspect on a feature game, it just fits so well
how do i get the big room doors open?
You need the key for them, i believe its inside the Book room or Bear room (it has a trophy on top of the door) and its called Garden key.
If you mean the other door unfortunately i dont think it can be open.
