Certatio API
This is one half of a browser minigame built in September, 2020 for a mandatory University project.
The repository of the other half, the web application, can be found here.
At the time this was built both of the authors were very inexperienced programmers, but the project landed us a good grade, and that's all that mattered then.
If you stumbled upon this page through pinned projects I'd advise just skipping it. The project being pinned is just an unlucky consequence of most of our current work repositories being private or being on BitBucket - or most likely both.
