Lambda Lantern 😃

What is Lambda Lantern? 🤔

Lambda Lantern is a game made with PureScript, PureScript Native, and Panda3D. The premise of the game involves collecting and using functional programming patterns to solve puzzles and ultimately escape a dungeon.

One of the purposes of Lambda Lantern is to demonstrate binding PureScript to C++.

Lambda Lantern originally started as a GitHub Game Off submission.
