About

The game is called Futoshiki.

Here's what wikipedia says about it:

Futoshiki (不等式, futōshiki), or More or Less, is a logic puzzle game from Japan. Its name means "inequality". It is also spelled hutosiki (using Kunrei-shiki romanization). Futoshiki was developed by Tamaki Seto in 2001.

The puzzle is played on a square grid. The objective is to place the numbers such that each row and column contains only one of each digit. Some digits may be given at the start. Inequality constraints are initially specified between some of the squares, such that one must be higher or lower than its neighbor. These constraints must be honored in order to complete the puzzle.

The project is built with an amazing game framework called raylib.

The game is complete with an in built level editor. The game engine is written in C++ and has some features I am proud of!

Ideas to explore further

• Using the github repo as a central level database, and fetching all the levels at the start of the game.
• Getting the community created content through pull requests.
• Making this project cross platform:
  • Scripts for building on Linux and Mac.
  • Removing the WinMain from the code.
• Find better solutions Level Selection and how it tries to rename every single level if one of the in betweens are missing.
