I dont think it was worth it
The galaxies that i set were the largest possible, i tried two at first then progressively got to 5 at a time. It was pretty neat watching them collide with each other. One of the problems i think it has is that after a certain period of time elapsed the galaxies would reset whether or not they had collided yet or not. Also after they collide completely the entirety of each galaxy disappears. Not trying to bash this app, it is interesting and fun to play around with but it needs some fine tuning and additional settings to make me feel like i didnt just buy an app that i will uninstall and never use again. If anything get the lite version and play around on it for free.
