Loved the pixel art and custom battlers. Would be cool if you also found a pixel-style font to really sell the art style! The RPG 8-bit perfect collection has some really fitting music for this type of aesthetic! The town maps I found to be a little too big/empty with too much negative space - shrinking them down in size a bit would probably go a long way.
I do like the world blending magic and modern technology, and had fun blasting people twice in the face with the shotgun.
The writing I found to be funny and enjoyable too!
Unfortunately, had an error at the final(?) boss after returning the crown:
Well done!
