Roll through a space shaped by your movement and defeat every enemy in sight.
Every 10 seconds, the world switches between "build mode" and "action mode".
Use the shape of the path you build to your advantage.
Killing some enemies may requrie abilities you gain from others.

Red "Cannon" pyramids yield their guns when rolled over in action mode.

Blue "Hoppers" transfer their jumping capability when killed, and cannot be safely rolled over.

Be mindful of golden "Ephemerals", because, while they may not be dangerous, they're wily and impervious to bullets! Trap them with your path and jump over them to destroy them.

When all enemies are gone, you've won the game! Good luck!
