Orb Survival

Red orbs are closing in. Collect yellow orbs, stay alive, and outlast everyone else.
Orb Survival is a fast arcade survival game for 1 to 4 players on a single keyboard. Play solo or with friends, in three different game modes, with optional bots that help (or compete with) you.

## GAME MODES
**Chase**
Red orbs hunt down the nearest living player. Keep moving, collect yellow orbs and use your abilities at the right moment.

**Random**
Red orbs fly in random directions and bounce off the arena walls. Less predictable, more chaotic.

**Shooter**
- Solo:
you stay in the center and aim with the mouse. Click to shoot the red orbs before they reach you. Enable bots to get five purple allies that use shields to protect you.
- Multiplayer:
all four players can move, and shooting automatically targets the nearest red orb. Red orbs spawn twice as often and move faster.

## NOTES
- Best played in Chrome or Edge on desktop. High score saving relies on the File System Access API, which other browsers do not support.
- A keyboard is required for multiplayer.
- Sound is part of the experience, so turn your volume up. Good luck, and don't let the red ones catch you.
