About

World of Haiku is a gamified cyberpunk experience that teaches you real-world hacking skills and tools as you advance through the game missions, tools like Nmap, John The Ripper, Hydra, Curl, Ssh, Dirb, MD5, and others.

The game contains a simulation of a fully-fledged operating system desktop experience, a GNU/Linux inspired terminal, a running interpreter of commands, a file browser, file editor, and other tools.

The international team behind its development is composed of people from all around the world, of countries like the United States, Ukraine, Brazil, Georgia and Japan.

About

Peek Obj - Renders a 3D object from an .obj file, from scratch, in the terminal. All computation is done in the CPU, single threaded, using matrix multiplications for transformations / projection and Bresenham's line algorithm to draw the triangles.

Tested across multiple terminal emulators.

Technologies

Made in pure Rust, uses a library to work with different terminal back-ends.

About

A Runner game for desktop and web desktop platforms, control the goblin with the arrow keys or W, A, S, D, dodging the obstacles until he gets to the finish line. The demo uses level design instead of procedural generation.

By losing the game repeatedly, the game changes the final message to the player, to "encourage" him to keep trying (the hard difficulty is actually hard).

Available in English and Brazillian portuguese. The entire interface can be controlled by the keyboard.

About

Implementation of the game "Peg Solitaire" in 3D for the web, works across desktop and mobile browsers.

The goal is to move the pegs (by clicking the brighter ones) to consume the adjacent pegs, the same way as the Checkers Game, while trying to make sure that in the end, only one peg remains on the board.
