YO THIS ACTUALLY GETS RECOMMENDED ON THE FRONT PAGE. CONGRATS DUDE! HOPE YOU ARE DOING WELL!
I also had this bug with mass in tutor. Every time
Very cool game
Oh, shit, I never fixed this on demo version I'm sorry!
I love your game—just watching the stars interact with each other is already really fascinating. By the way, have you considered releasing a Simplified Chinese version? I’d be happy to help with the translation if you’re open to it. If so, I’ll send you a DM on Discord :)
This is an amazing simulation, trust me I'm a complete sucker for these games! I will say, if you needed a debugging, the temperature scale increases regardless of whether I hold it to the right or the left of the centre. But otherwise, I love it
I know this might not be a thing you would like to do, but if you would like to play a way more polished version, I recommend trying it on Google Play
Sorry I never saw this. I would love to!!
Super Super cool, but how do i add rings and custom clouds?
I got kinda sad when I saw TON 618 but it did absolutely NOTHING. It can't be put in the simulation, even an empty sandbox one :(
Dude this us the best space game for mobile ive come across ever i think its pretty much a mobile universe sandbox and keep up your amazing work
If you're coming from the Google Play version, Thanks but if you are not, you should install it from there because Itch.io is out of support
Im playing on google play
Made in Heaven.
BEST GAME EVER
Agree
This is so cool, is it free on Steam?
No it will be 5$ but will have like hundreds of more features
Completely fair, just thought I would ask.
i'm trying to play on Linux but it keeps saying that the .pck file is missing and i can't find one anywhere
Fixed
Tysm
tôi nghĩ là tôi khá thích nó đấy
I don't know a ton about planets, so I could very well be wrong, but I think the sun's data is wrong? In-game it says it has a density of 411.63 g/cm3, but wikipedia says it's closer to 1.408 g/cm3. I think it's mass should also probably be 1 M☉ rather than 0.1669 M☉
What an amateur developer. I expect this to be remedied very soon.
I also get bug in tutorial with mass on first planet :( Webplayer
you forgot to embed pck

It is embedded it's just that it does not want to work on most Linux distros. Try running the windows version with compatibility layer like wine
hey a bit of a bug, during the tutoral, when i edit the mass it doesnt move on
This bug has been in the game for a while but I still can't see where the problem is because it only happens every like 100 tries
ok thanks
why is europa called europe
Will be fixed in the next update.
I little bit crash it, but still love it
The coolest game i've ever played
I think the game is really cool, what if you added a feature where the planet look actually changes based on what you do to it? like if you put earth too close to the sun the planet will burn over time and turn black
Download the game. The change you want has been there for 2 weeks
Attempting to run the linux executable (snapshot 1w16) on EndeavourOS (Arch Linux) results in this output and fails to launch the game.
So… missing some other files?
r.i.p web version
Practically a fun and cool game to play when you're bored
(Edit: I'll give this a 10/10, It couldn't get any hate)
im not any kind of cientific but its kinda impresive, i made a black hole colapse against an alpha centauri and it run like super fast, then i start putting random moons and planets around the black hole in movement and it was like, pretty colours
it is very laggy on web. maybe you could fix that?
What are you playing on? Because I can run this on a intel celeron n4000 (26 fps in web)
For me its very smooth... :D (Playing on 9600x)
really cool & it reminds me of universe sandbox ²! a spanish translation option would be nice though :D
I placed two black holes and it crashed hahahhahahahahahhahaahaa
nah fr this is rly fun
Agree, it is a fun and cool game to play when bored
please add like physical changes to the planets like make them have oceans when theres more water vapor and ammonia oceans when there is more ammonia in the atmosphere i know it might be a big ask though
Been working on a system for about a week but it needs a lot of hight maps so it will take a long time but next update will be great
epic i will be enjoying playing this thank you.
youre a goat totoriel
I might be late but the update has been up for a few days download it because the web version can't support it
Hey uhhhh discord link has expired or something, could you renew the discord link or give it to me? I want to join the server and I want to support!
Well Discord lied to me lol
https://discord.gg/zwKeS7Q6Hx
What you need is an epic planet explosion crashing into each other. L like what they show in those science Documentaries of what happened planets crash into each other. Then this well be a really good solar sandbox
AAWWESOME GAMR
Rage bait?
It's probably ragebait
In all honesty it would be cool if we were told to make our own universe from pure nothingness as if we were making it from the big bang itself
Bug: the tutorial pop up never goes away, even after following the instructions
it happened to me as well!
How can I download the HTML version? (Not part of files in patch 1.5)
As of right now no but I will be sure to make a .exe,.apk,.x86 tomorrow morning (it's 3am I'm typing this from my bed) good night
Even if I forget the game has a version checker so it will tell you when it's released
It's up!
looks interesting but it's currently unaccessable, keeps redirecting me to a pop-up and then saying unauthorized site detected
Yeah Firefox is broken as of now but you can just download the HTML or you know exe or apk or x86 (Fixed with snapshot 1w5)
Sadly i can't start the web version of the game.
Every time i press the "Run Game" button, it redirects me to "itch.io embed-upload" link and the game says "Unauthorized Site Detected". 😢
I know that is a problem and I'm working as we speak to fix it!
I have already found why it does it, it's because itch.io does not always use the window and it gets the wrong site
(Fixed with snapshot 1w5)
thx! you are the best!
