Bullet Hell

Controls Your ship fires upward automatically. Drag on the board (relative movement, so your finger never hides the ship) or use ←→↑↓/WASD. Only the tiny dot at the center can be hit, so you can slip between bullets. Each hit on the boss scores 1 and a kill scores 50; the next boss is tougher with more patterns. A hit clears all bullets and gives 2 seconds of invulnerability (3 lives).
