It was based off of a tutorial I was watching while getting an idea and the idea sprung into my head. I couldn't figure out a efficient way of making the bullets go pass the mouse position but I did turn a bug into a feature.
The concept was if you want to kill ghost it would make sense to use their substance against them. So you had ghost bullets but the problem was you had a soul in those bullets so the only way to take them both out is to kill them both on impact. If you miss the soul would break free and come after you for capturing it. So it was a cause and effect style game.
The feature was an interesting concept that I could probably use in a bigger scale game once I figure out how to get the projectiles to go pass the mouse position. Thanks for the feed back on my first game published!
