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.)

I hope you were able to learn a few things through making this prototype! From the look of it, you've clearly learned how to use a grid-based framework to generate random interiors, and set random cells in the grid to emit enemies with basic line of sight, collision with each other, and pathing.  That's heaps of progress! You know, there's something satisfying about having a horde of little monsters follow you like this. You could have a game where you need to get them to follow you to the end of a course but keep as many as possible alive! Very Pikmin. Hope your first experience with procedural generation is something you can keep on with in future games! 

Let me tell you what: keep working on it, you got a very basic boilerplate here, you just need to complete it.

Hey!! Just a reminder to update the game name even though I'm sure this is not quite "the title", I'm just going through and making sure!
