I’ve attached a simple Windows application that I wrote many years ago (should still work on a Windows machine). Uploads of .exe files aren’t allowed, so I changed the extension to .pdf. After downloading the file, change the extension to .exe. The file is safe.

The goal of the application is to move from a starting point through an obstacle course and get to a destination point. There are many approaches to solve this problem, and this application uses a non-deterministic approach. Run the app and click anywhere on the screen to load a new set of obstacles.
