Slime Ranchers on multiple PCs and buy only once?

I have a little question about the game "Slime Ranchers"! If you buy the Slime Ranchers game on a PC, can you do that on another PC without buying it again with its Acc? I do not know how to formulate the question… Eg. If I buy this now on a laptop so online and then I play it there first. Then at some point I want to make the game on another PC with the progress that I already had and I do not want to buy the game again, is it?

Yes, as long as you sign in to your account on the other PC
