As a bit of a forewarning, this was a project I had posted to itch.io a few months ago. I've circulated it a bit back when I first completed it but recently have been trying to put it out there more earnestly.
Terrier is a puzzle-based exploration game for Windows, in which you play as a small dog that must come to the aid of the land's inhabitants while searching for its owner. Following a classic Apple Macintosh aesthetic, both monochrome and color versions are available.
You can download the game from my itch.io page at https://fyndr.itch.io/terrier
