I enjoyed the gameplay and the audio in general. The knight's "voice" is a bit annoying to me though lol, the mage's "voice" is ok. The boss attack designs aren't bad either.
Although I know the dialogue is part of the interpretation for the theme, I think it's a little bit too much hand-holding. Those things could be figured out naturally as the game goes on, or in a normal game, it would be introduced naturally as the player progress instead of throwing them straight into the final boss fight lol. But yeah, I think this was a case of the game suffers from its strong tie to the theme, rather than the theme adding to it.
