nacn.app
nacn.app publishes free pixel-art games that you can play right in the browser on your computer or phone. No account and no app install needed. Each game moves forward little by little, a day or a week at a time, like keeping a diary, and the choices you make shape how things turn out.
A diet simulator where you pick meals, exercise, and sleep each day to guide a pixel-art character to a goal weight. Weight and body shape change day by day based on resting metabolism and calories in and out. Rainy days, weekends, and happy hour invites make sure not every day goes to plan.
A strength training simulator where you plan a week of workouts, food, protein, and sleep and see how strong you can get in 12 weeks. Lean mass, body fat, and your one-rep max on lifts like the bench press change day by day. Train without rest and fatigue can lead to injury; stick with the same plan too long and you hit a plateau, just like real lifting.
A shop-opening simulation: choose a city, a location, your budget, staff and prices, open a boba shop, and see from 7 days of business how long it would take to earn back your startup cost. Each morning you just check the forecast and decide how much boba to cook, and the day runs by itself. Rent, wages, selling out, throwing boba away, and forecasts that miss are all part of it. Pick a city in one of 10 countries and regions, including Japan, Taiwan, Hong Kong, Singapore, and the USA.
Pick your country and the year you were born, and time rolls back to the year you started first grade. Relive the toys, video games, music, and events that were big each year from 1970 to 2025 in the United States, the Philippines, Canada, Australia, or India (players in Singapore can pick any of the five), each with its own school system, choose your path after each school, and grow up all the way to graduation. At the end, your memories from every grade come together in a "life timeline" you can share with friends.
A hero who lost their life in modern-day Japan is reincarnated in another world and tries to survive for one year (52 weeks). Answer each week's event with a choice, and your stats, allies and the ending all change. The world and your skill change every time you play, so no two lives are ever the same.
Every game on nacn.app is built around one idea: you should be able to play in a spare moment just by opening your browser. Each game runs inside a single web page, so there's nothing to download and no account to create. It plays the same on a phone or a computer.
Your progress is saved automatically in your browser. If you close the page partway through, you can pick up where you left off next time. What you enter in a game, like your weight, is never sent to our servers.
The look is retro pixel art that recalls classic game consoles. Characters and backgrounds change with what's happening in the game: in Diet Diary, your character's body shape slims down as you lose weight, in Muscle Diary, their shoulders get broader as they build muscle, in Nostalgia Diary, the TV and phone in your room change with the era, and in Isekai Diary, the seasons and the monsters you meet are drawn on screen.
New games will be added to this page as they're ready. Feedback and requests are welcome through the contact form.
