I didn’t get a prototype done last week, but I did one the week before. It’s basically the extension of Gravity, my previous prototype. I finished that one in about 7 hours and took 5 more hours to refine the underlying technology.
Just as the week before, I did this one in JavaScript using the HTML5 Canvas element.
The original idea was to let the player start a rocket from a planet into orbit, but again, I didn’t get that far. I started with a rocket in space and got carried away working on the underlying framework, that is starting to develop out of these prototypes.
But who cares, I’m happy with it, it was fun, so I can count this as a full success. Take a look at the source code or check out the prototype. You can control the rocket with the cursor keys: Use left and right to change direction, up to accelerate.
