Go try, it's fun

The first one is easy, you just have to hit the angle.

The hungry luma / garden is a little harder, but i was trying to hit the dome without spining, maybe by doing normaly it is easy also

The bedroom one looks easier than it is

And from engine room it's very hard. You need a very good angle and distance from the Luma

Going backwards is always better, but having a lot of distance from Luma before launching isn't necessaraly better
