Ragelang

A rage-inducing programming language where unsupported characters fall. Built for Langjam Gamejam 2025.

What is Ragelang?

Ragelang is a unique programming language designed to give developers the frustration and rage that players experience in rage games. In Ragelang:

• Every character must be supported by characters beneath it, or it will fall
• Unsupported characters fall like in a physics simulation until they land or fall out of the program
• A foundation row (marked with #) acts as the ground
• Characters can be supported by characters directly below or diagonally adjacent below

Example

print("Hello, World!")
// | | | | | | | | | |
//  | | | |   | | | |
//   | | |     | | |
//    | |       | |
//     |         |
##     #         #
