I liked the "distance to the moon" meter. I felt much more encouraged to try again when I knew how close to the goal I'd got.
I feel like there weren't many interesting decisions to make. Maybe add some trade-offs? For example, fuel quantity vs quality, with more fuel meaning more weight. Or maybe you burn up if you accelerate too fast through the atmosphere, so there's more to do than just hold down the button. I just rested my phone on the spacebar and left it on "autopilot"...
The concept of putting a goose on the moon is really wacky, and the victory sequence was a good reward.
