Gapland

A (relatively big) shape appears in the center. Easiest to start with a circle (and resemble a planet), but could be anything.

Rotate it by swiping your finger across the screen.

Stuff flies in from the edges. (Not necessarily left/right, not necessarily in a straight line.)

React to it!

Some things are allowed to hit the edge.
Other things should be deflected. (You get a force field, or cannons, or something at some point on the surface.)
But many things have to travel into the shape => inside of it are certain locations, you need to uncover those and then allow stuff to come at it

Is it possible/better … to start with a pre-holed shape? :p (Which would be done by just “simulating” some hits in advance. During the game, this cannot change anymore, and it’s all about guiding stuff towards the right spot.) => this could be a whole different mode.

How do you win/lose? There are many ways to score points. Or you just need to “stay alive” for a certain amount of time. When you win, you move to a bigger planet, with more dangers, and the game becomes faster.

You lose if the core of the planet is blown up / the planet becomes too small.

IDEA: Once you’ve unlocked the next level (either by playing well, or by buying it with an ad), you can start from there. This has the same function as a “head-start”, while also working as different biomes and clear targets to aim for.

A One Button Game?

If alone, your planet will rotate clockwise automatically, but pressing/holding your button makes it rotate the other way.

If with more players, then each planet gets two players:

Player A’s button rotates the planet clockwise
Player B’s button rotates the planet counter clockwise

When more people log in, we can just place new planets, and the camera zooms out to fit.

Implementation

Use Godot’s Geometry2D functionality for all this => when something hits the edge, it explodes (like in Worms) and changes your shape.

Make the gapland a static body. When turning it, instead rotate the whole world.

The other bullets are kinematic/rigid bodies. They should register collisions and do all that stuff. (This easily allows the gapland to be a concave physics shape of any kind.)
