I just found a really weird bug on both of my Hollow's Space Invaded and Hollow's Space Invaded Part 2

I was just playing them and I saw my score kept going up without shooting a single bullet. Is this wrong with my collision code? is it something else? Because I have no idea how to fix it. I really hope someone can help me.
