Thank you for this uplifting comment.
It is true that I did design these levels perhaps a bit too difficult. I wanted to to encourage the player to learn how to move around as fast as possible.
Right now I see two options to improve your player experience.
Would you prefer there to be more sanity to finish stages or an option which makes the sanity only go down when hit by monsters?
(Not guaranteed to implement one of these, but it helps coming up with a way of making the game more accessable.)
Once again I would like to thank you a lot for this feedback.
I am also thinking of toning the difficulty down and unlocking a hard mode after finishing a certain amount of stages, (imagine world 1).
