Chillu vs. Butterflies
Chillu vs. Butterflies is a free arcade survival game where Chillu must dodge a swarm of colorful butterflies that periodically charge in for an attack. Move Chillu with the keyboard or a touch joystick, avoid incoming hits, and outlast the swarm as the butterflies fight and eliminate each other on their own. Play instantly in your browser — no download, install or account needed.
Story and goal
Chillu is dropped into a field of up to 16 uniquely colored butterflies. Every few seconds, one or more butterflies breaks off from its flight path and charges straight at Chillu, and getting hit costs Chillu a life. Meanwhile, the butterflies collide with each other independently and gradually thin the swarm through their own fights. Colorful flowers drift across the screen; any butterfly that touches one gains an extra life, keeping the swarm dangerous for longer. Chillu wins by surviving until every butterfly has been eliminated. The game also supports a Chillu Off mode where you can watch the butterfly swarm fight until one survives.
