An immersive, narrative experience that retells Joel Green’s 4-year fight against cancer through about two hours of poetic, imaginative interaction that explores themes of faith, hope and love.

"This is where we go to remember our son Joel, up through here along this path. We want to show you who he was, and how his life changed us. Can we walk here together for a while?"

A videogame developer's love letter to his son; a memorial to Joel Green; an interactive tribute to the loved ones of over 200 of our Kickstarter backers. Can you find hope in the face of death?

Using a mix of first-person and third-person perspective, and simple point-and-click interaction, we invite the player to slow down, look around, and immerse themselves in this deeply personal memoir.

What’s New

Version 1.0.4

This app has been updated by Apple to display the Apple Watch app icon.

This is a minor update that softens a few rough edges, especially about text getting cut off, dealing with icons, and touch areas on smaller devices. We also found a bug that caused the iPad mini sensitivity to feel far too high, so we brought it in line with the rest of the devices.

Editors’ Notes

We’ve seen death in videogames before, but never like this. Based on the developers’ heartbreaking true story, That Dragon, Cancer explores every parent’s nightmare through intimate, emotional moments that build to an unforgettable experience. By the end of this extraordinary tribute, you’ll understand the journey Amy and Ryan Green went through and just how much they loved their son Joel.

The Most Beautiful, Heartbreaking, and Inspiring Game in Existence...

I honestly don’t know how this doesn’t have a perfect 5-star rating on here, because it is the single greatest game I’ve ever played in my life, and I can’t thank the Green family enough for making it and sharing Joel’s story. It’s the most heartbreaking, beautiful and inspiring storytelling game I’ve ever played. I’ve lost family to cancer as well, and this perfectly shows every detail of what it’s like for the person who suffers from it, their overwhelming strength and optimism through it, and how family members struggle to cope with the loss after a fight is lost. I’ve never cried at any form of media, whether it be television or games, but this was the first one. I laughed, I smiled, and I cried the whole time through, because I knew it was real without having anyone spoil it for me. If you want to experience a truly beautiful story, then I recommend this above any game in existence. And if you have a heart, please donate whatever amount you can to vital organizations, like St. Jude Children’s Hospital and/or the American Cancer Association.

Beautiful in more ways than one

This game has literally changed my life and opening me to new understandings. I cried and I laughed and did it all again. To anyone who plays read the letters and listen to the notes. This game has a beautiful design and the story telling is amazing. Though It is a little Anouilh with over religious vibes but that's how the greens coped. It also has multiple bugs but still nothing major. And to conclude I would just like to say, to the creators, I'm sorry for the loss of your son. And these means a lot from an atheist but I pray he is truly in a better place or got a "do over" and became the amazing person Joel would of been if he was not struck by that demonic dragon. Thank you Mr. and Mrs. Green for making something so perfect and beautiful.

Btw the main glitch is in the first chapter when you go to the first section of whispering and there is no path out (visibly) and the area of the spot you Kia hit to escape is extremely small.
