Ooh, I haven't considered the ammo thing. I'll make sure to add it! I'll also try to make the restart prompt stand out more, thanks for your feedback!
Also, I'm saying this in the comments that point it out, but the music is not mine, I got it from here! It's properly credited in the game page, and specified when submitting in the jam. Music is something I have 0 experiencie in, but I'll try to make something on my own in the future.
