I will start by saying this game will not be for everyone. It is about minutiae. It can get pretty repetitive (more so than most simulators). I'm sure if you actually are a home brewer, you'll probably think this is silly.
But if you want an extremely a low pressure game that appeals to your inner OCD side, then you'll like this game. I like the challenging tasks (which are admittedly the most frustrating), the simple reward system is nice, and the ability to customize your space is fun. There are some annoying bugs still, like how the sound from the different tools (namely, the pumps) continue even after you turn them off/store them. The controls can be a bit annoying at times (do you hit ESC, do you hit the hotkey again, NO I DON'T WANT TO CONNECT THE TUBE I WANT TO SELECT THE ITEM) but those are probably more PEBKAC errors than mechanics.

Overall, I dig it. It was a good 'on sale' purchase.
