Yes but you can also compete on using as little throttle/booster as possible! IMO the perfect landing is one where you engage the engine at the exact right moment to touch down at <1mph, and you engage a booster only once in order to be upright. Engine and booster use aren't part of the score though.
The older commits were part of a previous idea that I abandoned, then a few weeks ago I deleted almost everything and gave it another try.
Thanks for playing!
