Halloween is coming, and the boss got a big update. If something feels off, leave me a comment on itch.io. It helps to know your platform and the world you reached.

What changed in v0.2.0

October 17, 2026

Halloween (Oct 24 to Nov 2)

  • Something spooky is coming to Pachinvaders for Halloween.
  • New Halloween challenge: defeat 310 ghosts for 31 credits.
  • Seasonal Look in Options lets you switch it off. The Halloween challenge only counts while it’s on.

Boss

  • Launching balls rapidly at the boss’s weak points rattles it and calls in minions.
  • Minions can drop a new Ball Reserve pickup.
  • Boss visual and effects upgrades.

Gameplay

  • Pachinko physics and the Ball Rack are now the defaults.
  • Enemies now breach at the shield line.
  • Later worlds have their own difficulty curve and tougher bosses.
  • Continue or suspend your run after clearing a world.
  • Bonus round and game over polish.

Cards

  • Cards got a pass to fit how many balls you launch now.
  • Heavy Magazine and Reserve Crate have 3 levels.
  • Ready Rack is a run card now.
  • Powerups bring their starting ammo again in each new world.
  • Ball, ammo and special shot cards give a lot more.
  • Beating a boss gets you a bonus card pick.

Options

  • New look for Options, with new tabs and a Credits tab.

Visuals

  • New start screen.
  • Cleaner logo and icons, and richer grid ripples.

Since the game is still in development, runs suspended in an older build won’t carry into a new one. Your upgrades, credits, Player Rank and unlocked worlds are kept.

About Atomic Petting Zoo

Atomic Petting Zoo orbit emblem

I love arcade games and the games I grew up playing on the Commodore 64 and NES. In fact, my NES stayed hooked up to my C64 monitor until about 2003, when I plugged in a PS1 and only got a black and white picture.

Later, the early Xbox Live Arcade and PSN download games took the biggest risks and had the craziest ideas, and I want to make games that hark back to that era, with a twist.

My first major release will be Pachinvaders. It started as an idea I had back in 2018: what happens if you cross pachinko with Space Invaders?
