Interesting concept, I had fun with this :)
I really like that you can destroy enemy bullets with your own ones, I think this mechanic/gun play could be implemented in a bigger game. It could be fun to use this with a machine gun or with more bullets or harder enemies where you have to shoot enemy bullets to avoid the damage and not something optional like in the game.
Also the enemy cats look cute and good, the only downside is that they can keep shooting after you kill them. The ghost mechanic is also fun, the way you have to die on purpose to keep progressing is interesting, maybe playing with the time you are as a ghost could lead to some small puzzle platforming like the few sections in the game.
I think the game is good without music because the atmosphere, like it feels it don’t need songs and the gunshots with the fire is enough, About the fire, I think the only thing I didn’t like is you can’t jump once you are in the floor where the fire is, making the ghost part a little frustrating because it means you need to die again to get unstuck from that place.
Also, great tutorial, I like it. I think I don’t have much to say outside those points, I liked this game :D
