Operation Lambda

Announcing Operation Lambda: a remake of the classic game by Bret Victor. Make your way through a distressed spaceship, rescuing hostages and deflecting lasers in 100 levels!

The remake implements the original (IIgs only) game entirely in Ruby, so anyone can play! It also adds a level editor, swappable tile-sets, and other niceties.

Where do I get it?

Operation Lambda is hosted on in my BitBucket repository. It is available as a Windows exe and an OS X app as well!

What do I need?

If you download the pre-packaged application, you don't need anything other than what's in the zip/dmg. If you're running it from source, you'll need

Anything I should know?

Operation Lambda is alpha-quality software! That means it'll probably crash sometimes, or just not do what you'd expect. Please, by all means, let me know if you encounter any problems.

Some machines have exhibited very poor performance, while others do fine. I don't know why yet! But, I'm investigating.

You can see the README and the in-game help for full details.
