The Heart's Illumination is a short romance/puzzle RPG made for the Touhou Fan Game Jam 4!

The contributors and their social medias are:

minute(Twitter), who did the art (and it looks beautiful).

Rae(Twitter), who did the story and gameplay (and assisted where he could).

Karob(Github), who did the coding (he's going to heaven for all his patience).

Aria(Bandcamp), who did the music (which is all so cool).

And several people on OpenGameArt.org who created sound effects that helped us save time.

In addition, a big thanks to the organizers of the Touhou Fan Game Jam, whose organization and friendliness made it easy to create a team, and who've made participating in this game jam to be a treat <3.

Art is really beautiful, sounds great too! I love Fuyu a lot, would love to see her more. Very very pretty game.


Very cute little game. The music is nice and the art is very pretty~ Would love to see more!

Hello, the game won't launch here, nothing happens when I doubleclick on it on Win 7 64-bit... Any clue on how to fix it? It looks super pretty already..


Hiya! I did some quick research. In order to make the game available on Mac, PC, and Linux, the simplest solution for us was to use dotNetCore. dotNetCore apparently requires your laptop to have some things in order for applications using it to work.

You may be able to install those requirements without changing your version of Windows. In order to try, check out the installations here for the C Runtime and here for a Security Patch. You might also have to install this in order for the C Runtime to work. 

If you don't want to go through all that (which I might not, in your situation), then try deleting it and redownloading it, or right-clicking on it and clicking 'Open.'

There were a lot of things we had to consider in the short time period, and we're sorry if you're unable to play the game because of it, but I believe one of the fixes I mentioned should work.

But also, thanks for liking the artstyle! Our artist can be found on twitter @minutekiwi and has done programming on the Heart of the Woods, soon to be available on Switch, but also available on desktop.

You're welcome ^_^ Also I love Heart of the Woods, I bought the game almost at release day and I haven't been disappointed ^_^

And thanks for replying too, As everyone here, I'm perfectly aware a perfect game is impossible to come with in 72 hours :) I'll just try a bit more :)


I managed to make the game run! Under Windows 7, I used the compatibility mode with "Windows 7" after installing both of the files you linked me to :) Thank you again, will play it right now!

I'm so glad you got it to work! I hope you've enjoyed it :)


Definitely did <3 I gave it the best mark :D The gameplay is really solid, visuals are awesome - people's faces are especially very expressive - and sound design is pretty cool too :) Also the writing is real nice :o

Hello, I'm the programmer for this game. I'm glad that you got it working with Rae's help. I'm also playing the game on Windows 7 64-bit, though I haven't had to use compatibility mode. By any chance, do you have Windows Update disabled? I thought that players normally wouldn't need to install any extra things to play the game.

It's indeed disabled on my 64-bit Win 7 :o

*Glares intensely, even though I also have Windows Update disabled.*

You might want to manually run Windows Update at some point to catch up on general security and compatibility stuff. There were a few programs I couldn't run until I had updated my system. (Also, I'm stuck with Windows 7 due to old hardware.)


Love the art style! The storytelling/dialogue feels real, and I like the inclusion of some dialogue trees! The music and sounds are nice, too! I also enjoy simply needing to avoid enemy attacks instead of also attacking, too. It makes for fun gameplay!


I really liked the art style of the game! The story is very interesting and the music really set the mood for the game :D

I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)


Such a cute game, Fuyu is great and her and Kokoro make an adorable pair! I enjoyed the music a lot as well. Everyone did a wonderful job!
