Nuts & Bolts Screw Puzzle is a puzzle game where the player controls a cat holding a piece of bacon, trying to lure a waiting dog below a wooden structure held together by screws and bolts. The objective is to unscrew the bolts holding the wooden structure in place, causing the bacon to fall directly into the dog's mouth.

Each level has two main challenges:

Guide the bacon piece to fall directly into the dog's mouth.
Unscrew all the bolts holding the wooden structure in place.
If the bacon falls out of the play area, the player loses. The difficulty increases with each level, requiring the player to unscrew more bolts and navigate the bacon through more complex wooden structures.

The game features two power-ups to assist the player:

Drill Power-up: Allows the player to drill additional holes in the wooden structure to access hidden bolts.
Screw Remover Power-up: Enables the player to instantly remove a bolt without having to unscrew it.
The goal is to complete both objectives in each level to progress to the next challenge. Successful completion of all levels requires both dexterity in maneuvering the bacon and strategic thinking to efficiently remove the bolts holding the wooden structure together.
