Well Keeper

Flappy bullet hell

Play as a lightning-charged mouse who flaps its ears to move. Fight increasingly difficult monsters with automatically fired bolts of lightning as your primary weapon. You’ll be on the edge of your seat through 30 distinct waves across three levels. Each wave is unique and has a different attack, making every encounter tense, unpredictable, and packed with action.

Powerful upgrades

Collect coins from defeated enemies to upgrade 24 different properties and unique abilities called “Wishes.” These include powerful new weapons, economic effects, weapon modifiers, stat boosts, and more, fueling a strong progression curve.

Epic boss battles

Conquer huge bosses at the end of each level. With layered attack patterns and multiple phases, these extended battles deliver a distinct challenge beyond regular enemy waves.

Immense power trip

When defeated, you lose your coins and restart from the beginning of the level, but keep your acquired Wishes. This makes you more powerful each time you begin a new run, creating a thrilling sense of exponential domination.

Distinctive flap-style movement

Flap left or right to move horizontally, and adjust your flapping speed to control altitude. You can also dash sideways to dodge tricky projectiles. This simple control scheme is easy to learn, yet offers expressive, skillful movement.
