I thought about the angle thing but was kinda lost about how to modify the throw algorithm. I will make some test to see if I can implement something along these lines. I am happy you ended up enjoying it :D
I 100% agree, i couldn't find an idea to make it clearer while jamming. You can unzoom with Tab and move the Camera with WASD as a work around, but it feels like a makeshift solution.
I wanted to add icons on screen border to help vizualize directions, but i got the idea too late
