Factory Town is super impressive, not only because it was made by one person - but also as a game in it's own right. It's a unique mix of automation Factorio-like and relaxing colony/city builders. I've been playing through the campaign which is a series of 8 maps with objectives. You start with a tiny town, and fulfil villager's needs by creating the automation and production lines to create the goods they need to level up and grow the town. It's well balanced in terms of production chains, there's huge freedom in how you build things (lots of multi-level building), unique ideas and it all mixes together really well. It's one downfall is a really ugly UI, but I still really enjoy it.
