It's simple - some levels don't have their own transition to previous ones, so here are a couple of ideas about that.
• From level 3 to level 1. Yes, at the very beginning there is a door that can't be interacted with. So once you have fixed the light on level 1, if you go back to it from level 3, the light will still be on and you will be able to loot items (the level generation is the same, so there are no questions)
Also, if you return to the door for level 1 after you've completed level 3, your progress on level 3 won't be lost when you interact door.
• From level 2 to level 3. Same thing. Same generation and the same progress.
• From level 4 to level 2 with elevator. (THIS IS AT YOUR DISCRETION, IT IS ONLY TO COMPLEMENT SUGGESTION)
Of course, some people will think, why? Why not? How does this interfere with the game? Just a nice additional.
Thank you for reading, if you are not agree - tell me below.
