I actually don't think you needed AI for the voice parts, the writing and art were great on their own to convey the tone and voice of the NPCs and PC. I really liked the combat, especially the timing windows after the enemy has attacked you to attack back. Health bars would be cool to give an idea of how close me or the enemy are to death.

Hey, thanks for the feedback. I personally think that voice acting adds a lot of immersion to the game, so that's why I went with that.
As for the health, you can see the boss's health as a red bar at the top and the player's health is displayed at the bottom left. Maybe you weren't playing it on full screen?
Edit: The game is finished now
