The letter arrives from your late grandfather. You leave the city. The bus drops you at a neglected farm with overgrown parsnip fields, a rusted watering can, and exactly enough energy to clear twelve tiles before collapsing into bed. By summer you are juggling blueberry harvests, a budding romance with the local blacksmith, and a descent into floor forty of the mine where shadow brutes guard iridium veins. That layered loop -- morning chores, afternoon socializing, evening combat -- is what makes the Stardew formula addictive.

Summer Engine lets you recreate that formula with your own setting, characters, and secrets. Describe how your crop economy works, sketch your town map, define the dungeon tiers, and the engine scaffolds seasonal calendars, NPC schedule walkers, gift-preference tables, and combat encounters. You focus on the writing, art, and feel; the systems wire themselves.

The best Stardew-likes succeed because every system feeds the others. Crops fund tool upgrades that unlock deeper mine floors that yield sprinklers that automate crops. Design those loops and the game pulls players through years of content.

• Solo devs who grew up on Stardew Valley and want to build their own version with a fresh setting or twist.
• Indie teams looking to combine farming, romance, and combat in a single cozy pixel-art package.
• Designers who want a proven three-pillar loop (farm, social, dungeon) as a foundation for their own mechanics.
• Hobbyists prototyping a Stardew-like demo for a game jam or portfolio piece.

• Three-Pillar Demo
