To build you just choose one of the three cells (numbers 1,2, and 3 on the keyboard), click the cell you want it to attach to, and drag to where you want to place it. Idk what you mean by the controls though, can you specify what the issue is? thanks for the feedback btw
for the first part, the only user issue i can think of is that you can only build more cells off of the building cells (the large circles with a green stripe down the middle). ill probably add a menu and tutorial soon. I'm fairly confident its not a glitch but idk. As for the second part do you think that the rotation is too slow or something? If you mean rotating individual cells then i don't really know what to say, the cells are meant to rotate by themselves and are set to always face whatever cell they are connected to. Sorry for the long thread im genuinely confused, and thanks for your patience
