I liked the ambiance and the core gameplay loop, but it ended too soon!
Burning things is always fun for me. I have always loved pyromancers in different genres of games. It was the same for the game and I enjoyed fighting against a monster with a flamethrower! I just wish the game was longer.
I liked how our character slow down while attacking, I think certain mechanics and enemy types could be built on that element. I also liked the simple attack pattern of the slug. However, it did not have readable anticipation frames so it required a great amount of attention to dodge it. I also liked how you included a well-fit ambiance sound effect!
Solid entry, I hope you build on the idea after the jam!
