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!
