So glad you liked it! The AI wasn't actually that hard to make. The A* Pathfinding Project for Unity (which you can find a link to on the game page) really made it pretty easy to set up an enemy that would track the player and avoid other obstacles. Highly recommend, even though the free version is limited to simpler kinds of spaces. The rest of the AI wasn't bad either; the script is a little over 100 lines. That's not to say it didn't a long time and a bunch of sleep deprived debugging lol, but definitely doable.
