Flicking is big in board-games right now.
Flick Em Up,
Decent,
Crokinole
I’m thinking…
A 2.5d phone game where you flick something like a fish.
Your finger’s velocity but not position controls your velocity.
You decrease to a stop in about 2 seconds of letting go.
You can apply brake by holding your finger still
Visually I’m thinking
a bit like ori and the blind forest but underwater -one point-light next to you
Loads of rocks super low-poly with good rgb, roughness and normal maps about 256 pix square
Rocks bounce you with physics rules
You bounce some rocks?
Exploration game
Water movement controls your movement?
