I took the time to extensively comment my entire game. I ended up with 885 lines of comments (wrapped at 80 characters!) for 1,570 lines of code. The code is pretty good for a 48-hour game and might give you a starting point for writing your own roguelike.

Topics covered:

• Python 3 in general
• Scene management
• Efficient drawing with BearLibTerminal
• Level generator with BSP trees
• Strategies for storing and using data
• Flexible system for simulation and AI
• Using pyglet for music and not graphics
• FoV using recursive shadowcasting via clubsandwich (post-compo)
