As assignment from a OOP class, some years ago, I made this game, inspired in a minigame from a Rockstar game, Bully.
It's ugly, but it works.
I'm a C/C++ programmer mainly, but I rushed to python to deliver it until deadline - I think this is a great proof that python is a great language to test/prototype ideas. It took 3 hours, from zero to this point.
To run it:
pip install pygame
python sumo.py
To play it:
Esc to exit. Arrow keys to move. Eat healthy food. Avoid fighters and rotten stuff.
I did it so fast and furiously that I didn't set an end or goal to it. If you want to do it, feel free to.
