I've heard about the Rubystein project. However, it is very old and written in Ruby 1.8 (I think so). Now there is already Ruby 3.x, which should be also pretty much faster even than Ruby 2.5. I want to make a game also similar to Catacomb 3D: Armageddon or Doom (using BSP) in gameplay, but completely with my own textures, sprites and story (although I have no idea yet how I will create different maps for different levels, I haven't found any level editors for Raycaster).
For example, there is the DUGA project, written in Python + Pygame. I would like to know if Gosu is inferior to Pygame in some way?
