It’s a very good start for someone just switching to Godot ! The procedural generation works well, as well as the spawning of enemies and their pathfindings.
Unfortunately it isn’t a completed game at all, but I hope you learned some things and that it made you want to continue learning, Roguelikes are very interesting to create because they have a lot of concepts that you do not find in all other games (like procedural generation, inventory management, etc.)
