[RMMV] NON-COMBAT GAME HELP!

I'm looking to make a non-combat game based around investigation puzzles and dialogue/interrogation puzzles. I need help with scripts and plugins that would work with this type of game, especially one where it gets rid of the equipable item screen but keeps the inventory screen for key items and such so you can combine items or use items for interrogations.

This game will be somewhat similar to Pumpkin Noir with similar mechanics, I know this. But, I've been writing the story for this game for a couple years now.

That's awesome. Thank you!
