I think the only criticism I have of Slime Rancher is that it's too fun.

I effectively speedran through the game, and then I got the final area, watched the credits roll as a beautiful song played, and it booted me back to the title screen.

I started playing a day after, and I was back at my ranch. I was able to unlock some gadget creation science lab, but I had no reason to.

I had beaten the game.

It was a brilliant experience, don't get me wrong, but it was over so quickly, and I don't know whether that's my fault, or the games.
