Tiny Glade

Tiny Glade is a calm building game from Pounce Light in which you create tiny dioramas of castles, cosy cottages and romantic ruins. There is no resource management, no combat and no goals, only a meadow, tools and your wish to build something.

You draw walls, towers and arches with the mouse, and the game adds small details on its own: ivy, flowers, candles and windows. Building is not bound to a grid, so shapes come out organic. There is Steam Workshop support, and the music and lighting set a relaxed mood.

According to HowLongToBeat (via DekuDeals), the main time is about 3 hours, and there is no data for a full run: you set your own goals. At about 2 hours a day (roughly 60 hours), a month is plenty with huge room to spare, even for detailed dioramas. The game is single-player, so it is fully available under the offline rental.
