This is very cool.
Out of curiosity, did you have any previous experience with game development to be able to actively critique the direction that the agent was developing towards?
Also, hope you dont mind, but I added it to the HN Arcade :) https://hnarcade.com/games/games/gothicvania
Thank you, and I don't mind at all!
I don't have any professional experience but I did build a pacman clone in Turbo Pascal (on MS DOS) back in the 90s. Also I've been playing games all my life so have a feeling for what's important - collision detection, walkable/collidable areas, speed/timing, some basic NPC logic etc. So that seemed to have been sufficient in this case :-)
