Chess games app made for Mobile Device Programming discipline

You can:

• Play chess offline
• Play online with other users. Create a challenge/lobby, and wait for someone to accept.
• Solve daily chess puzzles obtained from the lichess API. You can try these puzzles on the browser here. These puzzles get saved on the app, along with their states of completion and meta-data, like the ID and date.

Current tasks:

• Fix some bugs
• Add missing chess rules (pawn promotion and En passant)
• Simplify and organize some stuff
• Update AppDocumentation
• Add more functionalities

Special thanks to:

• My teacher, Paulo Pereira, for his teaching skills, good humor and personality and help. My teacher youtube playlist for the semester I did this discipline
• Joe Rogan for keeping me entertained while listening to his podcasts, which avoided me from crashing my dopamine while doing this project. And thus, keeping me focused
• Three 6 Mafia's music for getting me through the some stress I go through sometimes and for giving me resilience, hype me up, make me man up and put in work

Aftermath

This project proved to me once more that in order to do great work, you must be focused. It's way too hard to do 5 disciplines in a semester at the same time while you have 3 assignments/projects for each one, plus, given the fact that most of the time you have to do it all alone. Everything takes a lot of time to do and learn. I exceled at this discipline because I sacrificed others...
