(Chrome may falsely flag the download as malicious, but it's safe to ignore.)

1bitHeart is now available on Steam for $3.
The game will remain free here, but you can show Miwashiba your support by purchasing it.

Supported Platforms

The game's engine is made for Windows only, with no native support for other platforms. To play on Mac, you can try a general-purpose tool like WineBottler.


Make sure to extract the game to its own folder instead of running directly from the ZIP file. If you don't do so, any saves made will be lost the next time you run the game.

If the game freezes your computer on startup, it's likely caused by a problem with auto-installing fonts. Go into the Data folder, install all of the fonts, then delete the font files and try running the game again. It's supposed to install them automatically, but this seems to freeze some systems - deleting the fonts will stop it from trying.

If dialogue doesn't show up or uses the wrong font (which may cause cutoff text), manually install the fonts in the Data folder.

The parts where you must enter a sequence of buttons have had input issues, though they should be ironed out now. If Z, X, or C do nothing, alternative buttons should work: use Space or Enter for "Z," Escape or Backspace for "X," and Shift for "C."

Friend Guide

A guide to befriending people during Free Time. May contain some spoilers regarding who can be befriended and what presents people like.

Friend Guide

General Info

There are two categories of friends:
Those who are befriended as part of the plot, and those who aren't.

Plot Friends

They will be added to your Friend List in BitWorld upon befriending them in the plot.
However, you can still give then presents during Free Time, as long as they're around.
Getting them to 100 fondness points gets you a single Friend Event and their Friend Item.

Non-Plot Friends

These friends can only be befriended during Free Time at the end of a chapter.
They have four Friend Events, one every 25 fondness points.
The final event at 100 points will both add them to your Friend List and give you their Friend Item.

Note: The Friend List bios come with bonus Mutter logs if you press Confirm (Z/Enter/Space).
Also note the difference between Friend Items in the ITEM menu and the Friend List in BitWorld.

The number of friends Nanashi has at the end will affect the ending.
You'll be free to ignore friend-making entirely until the last Free Time with no consequences.
In fact, making no friends until the end will be the easiest way to see every ending.

Bad End: 8 Friends (plot friends only)
Normal End: 9+ Friends
Happy End: 25+ Friends


Each person has three "favorite" presents, which result in unique messages when you give them.
Two of the favorite presents will add 15 fondness points, and one of them adds 20. All other presents add 5.

*s mark the gift which is most cost-effective for each person. (Some have two equivalent ones.)
A * on the person's name means their "best" favorite item has a ratio worse or equal to 1 point : 2 bits.
You can get 1:2 with Umai?bos even if they're not a favorite. Thus, Umai?bos are best for them.

Mikado N/A; all gifts only add 5 points.

Some friend events that have yes/no questions will give you a bonus 5 points for picking the "right" option.
Which I won't bother making a guide for. In general, if there's an "honest" option, that one's better.

Special Notes

Finding Akashi:
He's on the bench on the right side of Honey Garden. Yes, only his legs are visible.

Misato's third event:
If you agree to her request, you'll be sent to a brief horror-esque segment.
Saying no will skip it with no penalty, other than not getting a 500-bit reward.
Each room has part of a message. Put together, it's "NEXT TO THE GIRL."
Examine the wall just to the right of the girl painting in the hall to find the way out.

Finding Kirara:
She appears in the Backstreet only after befriending Ryuuri.

Kirara's third event:
The last part was left "untranslated" because, while it is "readable," it's still basically nonsense.
The gist of the joke is that the conversation becomes increasingly incomprehensible, so I feel it works as-is.
Kirara's Mutter was translated because while it's written in a bizarre way, the content is fairly normal.
