This reminds me a lot of the first game I made more than 10 years ago (https://github.com/m-nez/gravity_slingshot). In my case you change the trajectory of your ship by adjusting the strength of stationary attractors in real-time.

Great game, though the controls on mobile are a bit too imprecise.
As you drag a hole, the size widgets should disappear so you can better see what's around it. They could pop back up again once you're done dragging.
Personally I'd rather if you had to press a button or something (or long press?) to add a new hole. I keep accidentally adding new ones when all I want to do is adjust an existing one.
Also spamming the user with the help screen right off the bat is a bit much. As long as they know it's there and can pull it up / dismiss it, I think it would be more fun to sort of discover the game mechanics yourself.
Note several of the first 8 or so levels can be accomplished with a single minimum (8) sized black hole. Eg. I liked the simplicity of doing that on level 6.

Being able to actually drag a hole makes it a little easier as well..! (Didn't even realize that was a thing as it was broken on mine...playing on desktop now)

Also a small bug: when rotating in response to the prompt to play in landscape, the button does not show and a refresh is needed while still in landscape

I resisted playing on mobile until I got home, and you're absolutely right that it's a whole other experience on desktop. In terms of addictive potential this reminds me favorably of that Seedship game, it's very simple, but powerfully "just one more round."

If you go on Amazon and search "100,000 whys", you will find page after page of essentially the exact same book. Presumably because asking some AI model "give me an idea for an educational book aimed at children" gave that answer.
I just asked ChatGPT to generate me an educational book title for children, searched the first result it gave me on Amazon, and found a book titled exactly that published a couple of months ago.
LLMs converge towards expected text which makes them really bad at creating novel interesting ideas when given essentially no information. You have to create the unique part yourself.
rcxdude 3 hours ago [-]
Yeah, for any given decision an LLM will tend towards a fairly limited set of answers across a pretty broad range of contexts unless you specifically steer it otherwise. It becomes pretty obvious when you run a lot of similar prompts through them. I remember one story of a teacher getting their class to use chatGPT for a creative writing exercise, and then getting them to read them out and compare them. What seemed like creative and novel choices from the LLM to each of them individually were actually replicated across most of the class.

I get that it's only a game, but all of these gravity games (with a couple of rare exceptions) ignore the fact that the black holes (or planets/suns) should be moving as well.

Kerbal Space Program didn't!
I wonder if it'd be much harder to simulate real gravity "spheres", with Lagrange points and all. But even without it, in simplified mechanics, planning slingshots and using Oberth effect had been fun.

This is the year of old browser (and/or flash) games making a comeback in some form.
Fun idea, but kind of maddening that I can click and hold to add mass to a hole but if i overshoot, i can't do anything subtract mass or delete a hole.
gschizas 22 hours ago [-]
Click on the hole. There will appear 3 buttons, one to add mass, one to subtract and one to delete the hole completely.
rapidfl 22 hours ago [-]
also need a way to increase the sim speed. 1.5x 2x etc
Definitely a fun game kudos!

The ability to subtract mass is definitely needed. All you can do is click “undo” and try again. You can drag the holes around too. Still pretty fun, I played 5 or 6 levels
trwhite 23 hours ago [-]
I just pushed an update. Click on the hole and controls will appear. I think you'll enjoy the later levels (10+)

iamwil 23 hours ago [-]
This is kind of a cool concept. It's like Space Golfing.
Another alternative is to make it like a turn-based Scorched Earth (Mother of all games), where you can either
1. launch asteroid size projectiles across star systems in a field of stars and black holes to it each other.
2. launch projectiles that then place black holes (perhaps either by timeout or signal--taking into account the speed of light!) to change the field.
It's a good start!

trwhite 4 hours ago [-]
The "no fuel" mechanic is very challenging. If you click on the "sector" button at top left and then click "I give up" the computer will show you the solution. It's all about making gates with two holes and then steering by adding mass to one
nilslindemann 17 hours ago [-]
I love it. The dragging of black holes could be improved:
* The black hole is not moved until the cursor has moved more than five pixels.
* The first time the black hole moves in the dragging process, it moves more than one pixel, afterwards one. So it is a small jump and then it moves smooth.
* The cursor icon changes to the drag symbol only after the mouse has already moved five pixels, not as soon as the mouse button is hold down.
* When the mouse is outside the draggable zone, but still in the game window, the black hole is not dragged along the border.

Also you can't move it too close to ship, but there's no feedback you're too close, so it looks it's just not responding.

- It would be nice to be able to manually key in the matter; on Safari desktop clicking uses up matter too quickly to set precisely.
