10 Seconds of Thrust by Kramin42

[raw]
made by Kramin42 for LD27 (COMPO)
A simple game in which you must get a spacecraft to the moon and back with 10 seconds of thrust. See how efficient you can be!

Here's a video showing how to do it: http://www.youtube.com/watch?v=7GLWTiEUxWY

It might be a little hard to see exactly when I'm clicking, but we wouldn't want to make it too easy now, would we? Rocket science is meant to be hard.

Also see this wikipedia page: http://en.wikipedia.org/wiki/Hohmann_transfer_orbit

And finally some general hints:

- Don't try to travel in a straight line to the moon, think with orbits.
- fire forwards and tangent to your orbit to travel further out, backwards to go further in.
- when approaching the moon, try to match its speed.

A game dont need to be complex for being fun! Good work, and happy Ludum Dare.

Hmm... The game is really hard, haven't been able to complete it yet.
It's a shame it isn't slightly more zoomed in.
You must have spent quite a fair bit of time on the physics, impressive, anyway.

Nice use of the theme, and very cool minimalistic idea. I do agree that it is very hard though, and I have not been able to get very far from Earth yet. Maybe a video or some tips could help making the game more approachable for clumsy guys like myself? Good job in any case!

Ok, I've added a video.

Thanks for the comments :) I know it's hard, but there wasn't really any way to make it easier (at least without sacrificing realism).

I wanted to make this game to scale but low earth orbit would have been only 0.6 of a pixel above the earth and the earth and moon would have been a third of the size they are, so you're lucky I made them bigger at all! :P

Interesting idea, but the unforgiving nature of the gameplay really kills the fun. Would be a lot more interesting if it was a little bit more forgiving, was a little slower, and you could actually see the distance you were traveling away from the earth right off the bat. It's hard to tell how to gauge distance and velocity at first.

Good application of the theme, the speed of the game makes for a challenge.

That's quite hard but very interesting (I haven't finished it, but I will try again)

Reaallly hard to control, not how I would have done it at all. But once you get used to it it's as fun as orbiting always is.

Can you put the JAR to download? I tried running the one at http://kramin42.github.io/10_seconds_of_thrust/10_seconds_of_thrust.jar but gives "no main manifest attribute, in 10_seconds_of_thrust.jar"

Ok, I've put a download there now. The reason you can't run the jar directly is because it is an applet.

I found this game really difficult, but I liked it! I could not record it however for my LD27 compilation video...
