I made this purely out of bordedom. Feel free to criticize this guide in any way possible. Also the gifs might be blurry because steam only supports gifs that are 2MB. Anyway Enjoy reading this stupid guide I made.
This guide only explains the Game Mechanics. Im too lazy to add the Team Minigame Topics.

Fall Guys is a platform battle royale game developed by Mediatonic Games.[www.mediatonicgames.com] The game involves up to 60 players who control jellybean-like creatures and compete against each other in a series of randomly selected mini-games, such as obstacle courses, survival, or tag.

List of Gameplay Mechanics:
Diving
Grabbing
Jumping

Grabbing is one of the game mechanics to do in the game. Whether it'd be for grabbing other players, grabbing on walls to climb up on, or throwing/picking up items.

CONTROLS
Hold Left Click [PC]
Hold the LB Stick [CONSOLE] It can be any console.

My Advice
When its on Jump Showdown[fallguysultimateknockout.fandom.com]. Grab people when it goes very fast.
You can also grab peoples objects making them drop it. It can be any object like Eggs[fallguysultimateknockout.fandom.com]
Penguin[fallguysultimateknockout.fandom.com]
Blast Balls[fallguysultimateknockout.fandom.com].

Diving is also very important in the game because you can avoid objects from hitting you, dive to areas where you can't normally jump at, and the most important one, Diving into Fans to reach the finish.
My Adivce
Dodge Items, and instead of jumping, find things to dive and grab at and maybe you could reach the ledge

Jumping is the most important game mechanic in Fall Guys. Jumping helps support Grabbing and Diving. If you grab something, then jump while throwing it it could go at a far distance, and if you jump and dive you can go towards farther distances.
My Advice
When a hammer, or pole is rotating counter-clockwise, pray that it boosts you and doesn't kill you.
