That was cool! It's a bit rough around the edges, but the art and monster design is charming, the soundtrack is cool, and the concept is quite fun. The amount of work put into character art and unique music tracks is staggering!
The mechanics are quite janky, but still pretty fun! I liked the concept of the fireball double-jump, even if was a bit difficult to use. I made it to the final boss... where I encountered the horrifying final game over screen. You fit the theme well, to say the least!
While the text gradient might make for good emphasis on key words, it's a bit hard on the eyes when applied to all of the text.
All-in-all, great work!
