Bloody Bubbles

Can you kill 10 unique bubble types in the room soaked with blood? Use your 10 bullets wisely as shooting the same type twice wastes a bullet.

Rules:
• Each bubble has a colour representing its type.
• Shooting a new colour adds to your score.
• Shooting an already-eliminated color wastes a bullet.
• You only have 10 bullets to eliminate 10 types.

Controls:

• Space: Jump

• F: Toggle fullscreen
• T: Toggle difficulty (hides bubble labels in hard mode)
• Esc: Escape the game
