nacn.appEvery 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. In the diary games, 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. In TsunaPop, the tiles are pixel-art sweets and animals, and in TsunaPeaks, the cards are laid out around a pixel-art clock.
Good to know before you play
- Price: Everything is free. There are no in-game purchases. Ads may appear on the page.
- Supported browsers: The latest versions of Chrome, Safari, Edge, Firefox, and similar browsers.
- Moving your progress: Progress is saved per browser, so it doesn't carry over to other devices or browsers. Clearing your browser data also erases it.
- Numbers in the game: Weight and calories in Diet Diary, and muscle and one-rep max in Muscle Diary, are estimates based on formulas from public health resources and research. The amounts and payback times in Boba Shop Diary, and the income and spending in Solo Living Diary and Newlywed Diary, are estimates for the game, too. Talk to a doctor or other health professional about real weight loss, training, and health decisions.
