Idle Bouncer

Idle Bouncer is an incremental game where you drop balls to generate energy with each bounce. The higher a ball jumps, the more energy it produces. You buy new balls and upgrade energy amplifiers, size, height and other attributes to increase your energy generation.

When your ball empire has generated enough energy, you can exchange it for meta-energy. This resets your balls and energy upgrades, but lets you change the world by increasing gravity, density and other attributes to speed up your run.
