How to play:
- Use Left/Right arrows or A/D to change your shape (Circle → Square → Triangle → ...). You can also click/tap the arena to cycle shapes.
- Portals rush from right to left. If a portal has a solid outline, match its cutout. If it has a dashed outline and a ! symbol, do NOT match.
- Pass a portal correctly to score. One wrong portal ends the game. You have 60 seconds—good luck!
