Thanks for playing the game and giving me this precious feedback :)
Secret rooms are challenging rooms which requires more focus and strategic thinking. Move limit is there so these rooms be harder.
I don't know which secret room are referring to, but all the secret rooms are open to go back from and when you solve "something" happens.
I've made a walkthrough for the game that I'll post in my devlog soon. In it I've written all the solution to all the content in the game. I can also send it to you if you want anyway.
