About the Game
Summer in Harmony was supposed to be simple.
Treehouses, comic books, and long days with nowhere to be.
Then Harmony Industries changed everything.
After the accident, the town begins to shift in subtle, unsettling ways. Streets feel unfamiliar. Neighbors aren’t themselves. With each passing day, the weirdness spreads.
In Welcome to Harmony, you play as Mikey, a kid fighting his way across a town slowly slipping into something darker. Searching for answers. Trying to reach his dad. Uncovering the truth behind what Harmony Industries unleashed.
Plan Your Turn. Execute Everything.
Build your turn by placing cards onto the timeline. When you execute, every action resolves from left to right. Once it starts, there’s no changing it.
You win by planning ahead, not reacting fast.
One Turn. Many Outcomes.
Not every card waits on the timeline. Some act instantly, letting you adjust your plan before you commit.
Enemies telegraph their intent, but they won’t act until you’re finished. Sequencing, synergy, and knowing when to lock in your decisions are what separate good runs from great ones.
Harmony Doesn’t Stay the Same.
Each run takes place over a single day. What begins in quiet neighborhoods slowly gives way to something stranger as you move deeper into town.
Familiar places feel different. New threats emerge. And with every run, you’ll see hints of how things could become much much worse.
Build a Deck That Can Survive.
Every run is a chance to shape a new deck. Add and upgrade cards, enhance your deck with relics, modify your cards with consumables, and watch your strategy take form.
No build lasts forever. The town pushes back harder the further you go. Staying alive means learning when to adapt and when to let a plan go.
Different Kids. Different Decks.
Each kid in Harmony has their own deck, relics, and way of playing. Some reward careful setup. Others thrive on risk and quick pivots.
Learning how each one approaches a fight is part of mastering the game.
Strange Things Happen Between Fights.
Not every stop is a battle. You’ll encounter strange events, make uneasy choices, and deal with situations that don’t have clear answers.
Sometimes curiosity pays off. Sometimes it doesn’t.
