Summary

Adds alien-wave, a row of three aliens attacked by a tank.

Thirty frames at 100x36. The aliens march back and forth, swapping poses each step and dropping a pixel at some turns, while the outer two drop bombs. The tank below dodges the bombs and shoots the middle alien first, then the left one, then the right one, and returns to the middle. Once the row is cleared a new one drops in from the top, which is where the loop starts again. The march speeds up with CPU load.

It is monochrome, so it takes the menu bar's tint color in light and dark. Each pixel is a 2x2 block, so the pixel art stays crisp at 1 pt per pixel.

The aliens (a cyclops, a bat and a spider), the tank and the explosion are original pixel art inspired by classic arcade shooters. They are not the sprites from any existing game.

Checklist for Adding a Runner

• I have read CONTRIBUTING.md and followed the steps described there.
• The runner is my original work, or I hold the rights to it, and I consent to its distribution under this repository's license (Apache-2.0).
• The runner does NOT contain third-party intellectual property (e.g., Pokémon, Mario, or other copyrighted/trademarked characters).
• Files are placed at runners/<runner-name>/ as <runner-name>-frames.zip, metadata.json, and preview.png.
• All frames are PNG files named <runner-name>-frame-<N>.png (numbered from 0), with a height of exactly 36px, a width between 10px and 100px, and all frames share the same size.
• The zip contains only the frames — no .DS_Store, __MACOSX/, or ._* entries.
• metadata.json contains the correct author, displayName, type (monochrome or color), and tags.
• preview.png is an animated PNG (APNG), 36px tall, at most 100px wide, and animates correctly.
• runners/manifest.json includes the new runner name and stays sorted alphabetically.
