The guide itself

I am so glad you asked! It's a lovely gravity game that borders on an art game.
Levels are procedurally generated and consist of an air based area and a water based one. You could play a few levels without realizing there's an under water area.

The faster you move the higher the goals are, and at a high enough velocity you start to sling shot constantly. This means you could clear several goals all at once and get a really high score. If you can't find the sweet spots you'll be hanging dead in the air.

Lore?

Pretty sure there is none.
