I absolutely agree with you, the game is addictive as hell, but it also has a little way to go in making the layouts more approachable.
We planned to have exit signs and other things to guide the player towards the next door but we didn't have time to get all of that done before the submission deadline...
It is planned for a future release in the next few weeks.
Glad you had a blast, and if you play again, please feel free to share your score in the comments :)
