Some suggestions

[Horus]

At first, thank you for this little gem. For a smoother ride without balancing problems and / or sickness, I suggest gentle non-linear acceleration and slowdown instead of abrupt stops and movements. (look at call of the starseed)
I did not notice the little presentations inside the capsule at first, because they were very low on waist height and behind me. Maybe there is enough space in the capsule to blow them up a little bit and show them more outside from the middle?
