Whiskerwood

Here is an excerpt from Whiskerwood's Steam description:

Carve mountains, traverse seas, and explore untamed new lands as you build grand cities – the ingenuity of the humble mouse is on full display in Whiskerwood as you establish elaborate automation systems to efficiently run complex production chains, all while dealing with the oppressive demands of your cat overlords.

As the dominion of cats spreads across the seas, the common mouse is sent forth from its home on perilous journeys. Arriving by ship on untouched islands rich in all manner of resources, the mouse must quickly establish a colony to meet the immediate and ever-growing demands of its feline masters.

The life of a pioneer is not an easy one – far from home without familiar creature comforts, you must learn to withstand and harness the forces of nature to provide for your colony and tend to the various needs and wants of your mousefolk.

The industrious mouse is not only a hard worker, but a clever one too – harness the power of automation to sniff out efficiency at every corner. Implement conveyor belt systems over great distances to carry goods up and down the colony faster than a mouse’s paw alone could, and pursue advanced technologies to evolve from a humble mouse-powered colony to a steam-powered mousetropolis.
