It's a lot of fun playing with the orbital mechanics in your game! A bit tricky to try and fly so close to the planets to get progress for completion but it's still a good time regardless, great job!

Submitted

Such a creative interpretation of the theme! I found the angle controls a bit hard in the beginning, but ended up getting it and had fun playing!

Submitted

Really neat concept well executed. Especially impressed by it on a technical level. Getting the simulation, the time changing and the checkpointing all working in under 48 hours is crazy impressive. Excellent work!

Hello fellow Bevyist! \o/ We’re now have at least three games made for GMTK with Bevy!

Initially I didn’t see any ship, but then I discovered you could zoom out :)

Really cool idea, definitely unique in the jam (of the games I’ve seen), and had some fun time trying to understand the controls and objective. Hard but fun, just like rocket science in real life so you totally nailed that aspect!

Submitted

This is the most creative interpretion of the theme! I love it.

Submitted

I like the music and simple look. I would have liked to be able to control the angle more precisely otherwise it was fun to play around. Great concept!

Developer

Thanks!

The music is Frost Waltz by Kevin Macleod:

An interesting take on the theme and a fun challenge. I'm sure my KSP experience helped. I struggled with the ship controls, not letting me be as precise as I would have liked.

Developer

What's missing is being able to change the referential to be that of a planet. Maybe also some more precise controls with SHIFT or something?

Glad you liked it!

Submitted

Very interesting with the time scaling. I enjoyed making it 1000x and just seeing what happens

Only was able to do it with about a deltaV of 1400. Quite a funny name for fuel

My main complaint would be how small the rings are around the asteroids. Made it quite difficult with the low margin of error we're working with

Amazing! Glad you tried your hand at optimizing it.

What's missing is being able to see the movement of the ship relative to a specific planet/moon. That would make it much easier to work with the orbits to touch the moons.

DeltaV is not the name of the fuel, it's a real metric that is used to measure by how much the ship can still change its speed. Delta means difference, and V means speed.

In a ship, Delta-V is to fuel what the distance autonomy is to fuel in a car. But because nothing is there to stop the ship, the distance is infinite. What matters is being able to control where the ship goes, hence the Delta-V metric.

My game is not really accessible to people that haven't played Kerbal Space Program sadly. I need to build a tutorial!


Submitted

This seems like a cool game, but I sadly could not figure out the controls or mechanics. The description didn't offer enough information on how to control the ship, and I'm not entirely sure how to reach the targets. I would've greatly appreciated an in-game tutorial that demonstrates what you're supposed to do; but, perhaps I'm just not smart enough to understand things, haha. Glad other people are enjoying it, congrats on finishing the jam!

Developer (1 edit)

You control the ship by clicking on it, keeping the mouse button clicked and dragging the mouse. This will change the speed of the ship so you can control its trajectory.

If you want another game that has similar control, check out Kerbal Space Program, especially the map view.

Without a tutorial or experience with a similar control scheme there's no way you could just guess it.

Regarding the mechanic: The goal is to make the ship go through the targets (the green circles around planets), by changing the speed of the ship as little as possible.


Anyway thanks for taking the time of checking this game out.

Submitted

It took me a while to understand how to play, but once I did I had a lot of fun. The way you get to see the dynamic of scale and time actually play made this really cool as well. A visual tutorial would have been nice but this is a very solid game. Great job!

Developer(+1)

Glad you enjoyed it and took the time to learn it!

It needs a tutorial that's for sure.

Submitted

I love it—it's very obviously KSPs' orbital intercept mechanics reimagined! It's a good fit for the jam, and it's executed well!

Developer

Thank you!

My main idea was inspired by the slingshotting idea in The Expanse, but indeed the game design took a lot of inspiration from KSP.

Maybe I'll build levels that better represent my intent.

Submitted

The time gestion with the fast forward and checkpoints are really cool.

Developer

😍

Submitted

Cool idea. I guess it was inspired by KSP?

Developer

Yup, clearly inspired by KSP and also some inspiration from The Expanse!

Not as polished as your's though!
