Hi! Looks very nice. I'm fan of rocketry and space exploration, this seems to be for enthusiasts.


Hello and thanks for the comment & encouragement, they mean a lot!
If you're up for giving it a try, we'd love to hear your feedback on it. The game is still very much in its prototype / experimental stage, so there is no need to be gentle about it

Hello! I would like to play all along, especially space themed games, but I'm dev myself as well, not much time to play games. However I guess I can give it a shot when I'll find some time (now it's 2am here in Spain). Btw, I'm also working on space exploration / rocketry themed indie title, but with different concept (so I hardly can be a competition). I'm in even earlier stage than is Corona Celestia.

Cool! Why don't you post a link so I can check it out!

Sure! In current stage it's just encyclopedia of early space exploration missions and rocketry, so I not created itch.io page for it yet. Later I want to add also gaming sandbox so I'll present it also on itch then. For now it's available only through my web page: https://vdapps.net/universequest .
Now, I'm really going to sleep, it's 3AM, I have problem with going to sleep at normal times. :D

Great Game! It contains many expansion options that drive you forward to play. Keep it up =)

Thanks for giving it a try, any kind of feedback is welcome!

Installing on itch.io desktop doesn't work, I'd paste the error text but itch doesn't let me highlight it.

I made a small fix and re-uploaded the file, hope that does the trick!

Works, thanks!

No problem at all!
Any first impressions?
