#dogwalk from #blenderstudio is a heartwarming free and open source miniature open world game! It lasts for maybe 30-40 minutes in all, as you explore a small winter landscape as a big, fluffy dog. The graphics and animation really convey a sense of a bright, sunny winter day.
Get it on steam or itch.io for free. And you can get the #godot source and assets of you want to play with it. This is really fun!
