[Slingshotter](https://slingshotter.space) is a spaceflight simulation game inspired by Kerbal Space Program. You design rockets and fly them to complete contracts. Unlike KSP, you don’t fly rockets in real time: Instead, you design a flight plan on a timeline, and instantly see the results as a complete trajectory.

This gameplay enables a number of cool things:

- Visualize the effect of every parameter on the trajectory.

- Change your rocket design \*after\* launching it.

- Tweak your launch to minimize propellant consumption.

- Do things in parallel, like reach orbit and land a booster (that you can then refly).

The game lets players develop a physical intuition of what it means to reach orbit, land a booster, rendezvous with a spacecraft, plan a transfer to Mars or Venus, or perform gravity assists.

Ah, my initial expectation was something more arcade-style, but it is more about planning and strategical thinking. Some “small” details were quite pleasant, like the timeline that zooms in and out well. (TBH, I even checked the leap years - they were 1st, 5th, 9th, …)

Generally, a short demo video would be nice, at it can show the gameplay and the visuals for people who have no time to experience the game fully.
