This game is about playing one small part in a much larger story. You only live an hour, but time and space in this game is infinite. You can only do so much in one lifetime, but the tech tree in this game will take hundreds of generations to fully explore. This game is also about family trees. Having a mother who takes care of you as a baby, and hopefully taking care of a baby yourself later in life. And your mother is another player. And your baby is another player. Building something to use in your lifetime, but inevitably realizing that, in the end, what you build is not for YOU, but for your children and all the countless others that will come after you. Proudly using your grandfather's ax, and then passing it on to your own grandchild as the end of your life nears. And looking at each life as a unique story. I was this kid born in this situation, but I eventually grew up. I built a bakery near the wheat fields. Over time, I watched my grandparents and parents grow old and die. I had some kids of my own along the way, but they are grown now... and look at my character now! She's an old woman. What a life passed by in this little hour of mine. After I die, this life will be over and gone forever. I can be born again, but I can never live this unique story again. Everything's changing. I'll be born as a different person in a different place and different time, with another unique story to experience in the next hour...

10 outta 10. Was put in charge of family security by grandmother as she gave me a knife when she died. I held onto that knife. Eventually one of my grandchildren was demented, and was screaming she was going to kill us all. She had to be taken out back. Her mother grabbed her and took out the back of the house. When I pulled the knife she ran. 10 minutes of her running around I said I gave up and ...

Brutal, horrible game entry experience. So many deaths. Every parent knows kids can pick berries off a bush as soon as they are old enough to walk to it.

zone map with biomes would be really cool. an icon at your point of death and ability to chose spawn location (whether eve or baby) maybe. also a timer before having a baby if you start as eve, or a baby limit.

Born to a lovely naked lady, she fed me through the cold times, sat me by the fire and told me stories of the past. She forgot to eat and died. Then I died.

An old man, tending the fields told me 'I don't have long.', 'Take over from me.' and was a pile of bones.

I took his hat.

Was born to a mother with two children. As I was sat on a bear skin I watched as a man in a cro...

Great game! So far I've learned to farm, hunt, make clothing and build a fire. My next time I spawn into a colony I'm looking forward to trying my hand at being a smith. I've spawned alone a few times and found old settlements where i lived and stocked them so if someone stumbles across it the crops will be seeded with filled water pouches and a stockpile of carrots. I've lived several live and ...

This game describes the love of mother and family

Nobody can live forever and their life is limited.

The only thing player can leave is their bone and what they've made.

But what in earth do they've manufactured or harvested good for themselves after death?

It barely effects players next game so It means nothing as well.

Everything is meaningless afterlife then ...

HAD AN AMAZING LIFE, sometimes you get so lucky, you learn a lot, and pass it down. Such a great feeling haha.
But yeah you will be unlucky spawning a few times, but if you get eve its really fun to go from scratch, and if you survive all by your lonesome, feels so good to find someone else to give everything to.
I feel a lot less selfish after living an old life and having kids lol... alw...

My mother was a baker in a big village. I grew up by her fire, learning to bake all kinds of pies. I continued her baking legacy after her death. Then I passed on the baking to a little boy in town.

Launching a game Off-Steam: Sales number from Week 1
March 9, 2018

I've heard it many times, from both friends and strangers alike (and even a bit from my spouse): "Jason, don't you think you're nuts for not releasing this game on Steam?" Steam has changed a lot over the years, though.


Back in 2011 when my game Inside a Star-filled Sky launched on Steam, Valve worked with me directly to pick a release date that had no major conflicts. My game was the only game that came out that day on Steam. I'll repeat that for emphasis: my game was the only game that came out that day on Steam. It remained on the new release list for almost an entire week, sitting there on the front page of Steam for everyone to see. That exposure helped this otherwise-unknown game sell 649 units on the first day and 704 on the second day, and achieve a peak of 43 simultaneous players on day two. For me, at the time, those sales number were huge and career changing. Of course, the normal drop-off and long tail followed, with occasional spikes during the sales that I participated in. But the biggest influx of players and revenue came during launch.
