By debugging your code I discovered that I had to pip install pytmx. And that you need a `time.` when `pygame.Clock()` in the main file. You also need to put data folder and graphics folder inside the code folder. In code\sprite.py you have to change 'get_frect' by 'get_rect', same with player.py
And it worked! Until I fell to the abyss because the player was too slow and had to restart the game because it doesn't respawn. So then I changed the player speed manually and it turns out it's a funny game to play (for the 10 seconds it lasts), as you bounce off the walls when you jump and walk at the same time.
I don't know if there is something more than this, because I just disappear when I escape the map.
