Only the current version so far — new entries appear as the game ships updates.
Open the app, and the rampage is already on.
HAMUMU, a round little hamster guarding its snacks, blasts away waves of enemies all by itself in this cute idle game.
- Just pick upgrades
HAMUMU aims and shoots on its own. Spend your coins on Attack, Fire Rate and Shots, and watch the screen fill with more and more projectiles.
- Coins pile up while you're away
HAMUMU keeps fighting while the app is closed (up to 24 hours). Come back and collect the haul.
- Six weapons to collect and grow
Rapid-fire Sunflower Seeds, piercing Star Candy, and the explosive Carrot Rocket. Push further to discover new ones, like the boss-crushing Acorn Cannon and the crowd-sweeping Wood Chip Blower.
Bosses drop weapon cards. Stack cards of the same weapon to raise its star rank, and evolve your weapons for new looks and more power.
Hamster friends join the fight along the way.
- Bosses and rebirth
A boss appears every 10 stages. If it's too tough, HAMUMU farms the stage before it and automatically tries again once you're stronger.
Go far enough and rebirth to collect Star Seeds, then start again even stronger!
- Easy to play
- One hand, portrait. No stamina, no sign-up
- Video ads are optional and only used to boost rewards when you choose to
- Battery saver and reduced-effects modes
