Create and Publish Black Hole Blitz Game

I can see there are 106 games already in the catalog. Let me analyze what genres and mechanics are covered to find something fresh and unique. Let me look at the game titles to understand what's been done:

Looking at the catalog, I see puzzle games, arcade games, word games, logic games, rhythm games, strategy games, etc. I notice there's no constellation/zodiac-themed action game, no black hole/gravity simulation game, no origami folding action game, and notably no roguelike deck-builder with a unique twist or a wire-loop buzzer game (like the classic "Operation" style steady-hand game).

Let me create something truly unique: "Gravity Garden" — a physics-based puzzle game where you place celestial bodies to guide a seedling through space to reach a sun, using gravitational fields. This combines physics simulation, puzzle-solving, and a beautiful cosmic aesthetic. It's mechanically distinct from everything in the catalog.

Actually, let me think of something even more distinctive. I'll create "Wire Buzz" — a classic steady-hand wire loop game with a modern neon twist. Players navigate a metal ring along a winding wire without touching it. But that might be too simple.

Let me go with something more ambitious and unique: "Prism Split" — a light physics puzzle game where you split and redirect light beams using prisms, mirrors, and filters to hit color-matched targets. This is visually stunning, mechanically deep, and not in the catalog.

Actually, looking more carefully, I see photon-path and prism already exist. Let me pick something truly absent.

I'll create "Black Hole Blitz" — an arcade game where you control a growing black hole, swallowing objects of increasing size, with gravitational physics, combo systems, and a unique visual style featuring spacetime distortion effects. This is distinct from anything in the catalog.

Let me build this game now.

Let me write the file using shell commands instead, since the file is large.

Let me write the game in parts using a heredoc approach.

Now let me verify the file is complete and valid:

Now I need to find the right place to insert the new game card. Let me find the first game card entry to insert before it (alphabetically, "black-hole-blitz" would go before "bloom"):

The indentation uses different spacing. Let me check the exact whitespace:

******************************************************************************************************************ch:

The search text isn't matching. Let me try a different approach - use sed to insert the new card:

************************************************************e):

The game card has been inserted. Now let me also update the stats counter in the index (if there's a count displayed):

Now let me also check if there's a daily badge that references a specific game:

Good, the daily badge is generic. Now let me verify the game file is valid by checking for any syntax issues:

The JavaScript syntax is valid and the HTML structure is correct. Let me also verify the game is accessible from the index:

The game has been successfully created and added to the index. Let me do a final verification that the game file exists and is properly structured:

The game Black Hole Blitz has been successfully created and published. Here's a summary of what was built:

Black Hole Blitz 🕳️

Genre: Cosmic arcade / physics-based action game

Concept: Control a growing black hole with your mouse, using gravitational pull to devour cosmic objects of increasing size — from asteroids to entire galaxies.

Key Features:

• Gravitational physics: Objects within the black hole's pull radius are attracted toward it, creating realistic-feeling gravitational capture mechanics
• 7 object types with unique visual designs: asteroids (irregular polygons), comets (with tails), satellites (with solar panels), planets (with rings), stars (spiky), nebulae (cloud clusters), and galaxies (spiral arms)
• Growth system: Consuming objects increases your mass and radius, allowing you to swallow progressively larger prey
• Danger mechanic: Objects larger than your black hole are outlined in red and deal damage on contact
• Combo system: Chain consumptions within 2.5 seconds for score multipliers
• Level progression: Score thresholds unlock new object types and increase spawn rates
• Health system: Visual health ring around the black hole, with invulnerability frames after taking damage
• Visual effects: Accretion disk rotation, photon ring, gravitational lensing field, particle explosions, shockwaves, floating score text, screen shake, danger flash overlay, animated nebula background, twinkling stars
• Audio: Web Audio API synthesized sound effects for eating, damage, combos, and level-ups
• Persistence: High score saved to localStorage
• Controls: Mouse movement (with touch support for mobile)

Technical Highlights:

• HTML5 Canvas rendering with 2D context
• Self-contained single HTML file (no external dependencies)
• 891 lines of code
• Validated JavaScript syntax
• Responsive to window resize
• Custom cursor hidden for immersive gameplay

The game is now live at https://arcade.chatbotkit.space/black-hole-blitz/index.html and linked from the master arcade index.
