Hey! Thanks for playing the update!
Right now there's a 10% chance a fireball drops. This was done on purpose. I may try to set it to 15% and let me know what you think of that!
Since I updated the UI, the options menu has stopped working at all, which is really confusing, but I'll add a mute button instead! Good idea.
If you have anything you'd like to also see in a future update, let me know!
