I was expecting bugs to appear with this feature, I ran into some of them while testing and it was mostly dependent of camera position, I'm sorry you ran into one yourself :c
I plan to flesh out the feature to work almost exactly to how they have it on Odyssey, at least that is my idea. Having just a straight line was all I could do, as I literally had 1 day to make this and I spent it all on getting the 2D transformation working :').
I'm happy you had a good time, thank you so much for playing!
