Draw to Defend

Draw to Defend puts a single glowing core at the bottom of the arena and rains energy orbs down from the top, each one aimed at the core. Your only job is to stop them: press and drag anywhere on the field to sketch a temporary neon barrier, and any orb that touches it bounces away harmlessly. On desktop, hold the left mouse button and move to draw; on a phone or tablet, just drag your finger across the screen.

Barriers are short-lived — each stroke fades after a few seconds — so you redraw as the waves keep coming. An orb that slips past your walls and touches the core drains its shield a little; that is the only way you take damage. Every orb you deflect scores points, and the counter at the top tracks your total deflects. Each wave sends more orbs than the last, and after you clear a wave the next, bigger wave pours in.

There are five waves in total. Clear all five without letting the shield hit zero and the defense holds — you win. Let the shield empty and the core is breached, ending the run. Nothing is shown being hurt in a realistic way: orbs are glowing spheres and a hit is just a light flash, which keeps the game friendly to a wide audience.
