Shape Rush
Match playful stationery monsters, then challenge an alien and a classroom ghost.

How to play
Shape buttons or keys 1–8. Match each monster from left to right. A shared starting shape stays pending as ? until another shape resolves the target. Switch between monsters while retaining their confirmed progress.
Scoring and rules
10 per shape + combo; elite +40, boss +100; 3 lives. Every 10 consecutive correct shapes earns an elite; every 30 earns only a boss. A wrong shape clears the board. An escape removes only that monster and preserves other monsters and their matched shapes. Both reset streak, pending specials and speed. Keep your score and unlocked shapes. Special defeats unlock one shape. Monsters appear 10% less often. Each boss appearance adds one shape: 6, 7, 8 and onward. Ordinary monsters alternate 1/2 after the first boss defeat, 2/3 after the second, and keep increasing. Elites start at 3 shapes and gain one per boss defeated. This progression persists after mistakes.
Feedback uses PERFECT / GOOD / MISS and scores. Leaving the tab pauses play; press Resume to continue.
Start with circle and triangle. Elites start with 3 shapes and bosses with 6. Every 30-hit streak queues a boss; each boss appearance adds one shape to its sequence. Each boss defeated adds one shape to normal and elite sequences. Defeat an elite or boss to unlock one new shape. A confirmed target has priority when its next shape matches; other monsters are also valid. Shared starting shapes show ? until another input resolves the target. With 1/2 and 1/3 monsters, pressing 1 then 3 defeats only 1/3. Each elite defeated adds 2.5% speed, up to 1.5×.
