Muscle Big Bang: Idle Clicker

"...Not enough load."

A few words from the Protein Sennin, and a skinny kid named Yamada starts training on the riverbank.
His first load: a 500 ml water bottle. Press REP! to lift, add exercises, hire coaches, then just sit back.
Before long he is curling fridges, deadlifting skyscrapers and carrying the Earth on his shoulders.

Muscle Big Bang is a pixel-art idle clicker about getting ridiculously strong. You can start with a single tap, and your gains keep growing while the app is closed. Play for a minute on a break, or spend hours making the numbers climb.

- FROM A WATER BOTTLE TO THE UNIVERSE ITSELF
Skinny → Gym → Household → Megastructure → Planetary → Planets → Stars → Galaxy → Universe.
9 stages with 10 exercises each: 90 exercises in all.
Bottle curls, fridge curls, jeep shoulder presses, skyscraper deadlifts, moon dumbbells, Sun bench presses, black hole curls... and finally, the universe itself.
Every stage brings bigger scenery and bigger loads, and Yamada's body grows from skinny to toned to bodybuilder to cosmic.

- THE CROWD'S CHEERS COME TRUE
"Got a tiny jeep on those shoulders?!"
Every chapter ends with a shout from the crowd, and in the next chapter it literally lands on Yamada's shoulder.
A jeep. A radio tower. The Earth. The Sun. Classic bodybuilding cheers, taken at face value.

- GAINS WHILE YOU SLEEP
Hire a coach and that exercise reps by itself.
Gains pile up while you're away. Collect them all when you come back.
"Rest is... part of training." — Protein Sennin

- WATCH THE NUMBERS EXPLODE
Thousands, millions, billions, and far, far beyond.
Stack up exercises to trigger Breakthroughs that multiply gains and speed.
Boosts, the Hall of Fame and Pumps push you even faster.

- SUPER RECOVERY (PRESTIGE)
The more you train, the more muscle memory you build.
A super recovery resets your training, but muscle memory multiplies every gain many times over.
Every run is faster and bigger than the last.
