A small 2d game made in 2018 with MonoGame and C#.
The player moves around a grid to try and collect more treasures than the AI opponent. The majority of the game was playing with tiles, sprite assets, and a pathfinding algorithm for the opponent.
You should be able to get this project up and running locally with a free copy of Visual Studio 2019 Community and then installing the MonoGame.Framework.WindowsDX package.
