I just started playing this today also. Only a few missions in, but really enjoying it. The amount of stuff you can interact with makes it a joy to play. You can tell a lot of love went into the game.
For example, I was cleaning up an area of a kitchen, and I released a bat. The bat flew at me, and I thought I was under attack as what usually happens. Then it quickly circled around, and it ran into the stove and incinerated. Just a tiny moment that has no reason to be in the game except the devs probably thought it was funny.
