need a buy all button ie buy this as many times as you can afford. 

feels a bit empty that "phone a friend" doesn't have any upgrades like the other autos.  

Buy all was added in an update (you right click an upgrade to do that). The phone a friend technically upgrades itself the more you use it, increasing the number of thrusts the friend can do, but I'll probably add some upgrades to the ability itself. Thank you for playing my game :)

It seems like the game will not start, it shows the Godot loading screen but gets stuck on it.

Edit: I tried to reinstall but it does nothing to help.
