Drafting out the Game Levels (Patreon)

So current task I am doing right now on the game is making drafts on the level layouts for the full game. Troubles always comes to thinking on what aspects of the layouts would work best for the game. Questions that are currently crossing my mind is...

1- What should be the limit to how many rooms should each level?
2- Should the Keys/Locks only be in non-obstacle rooms?
3- Should the stairways only be in their own rooms?
4- Should limit levels by 3 floors or should I go to 4?
5- Is it alright if levels might share similar layouts and room placements.

And the list of questions go on in my head. There is no doubt some aspects that I am overthinking and such, but in time I'll soon create some final drafts on the level layouts and once that is done then its time to create the levels in the game.

Anyway at least in the coming weeks expect to see me post updates on the draft work for the game. If you have any feedback/suggestions feel free to leave a comment.
