This uses the inverted assets that were added to the repo in commit d1a0522 to provide simple visual feedback when a button is pressed.
Previously, an enemy could creep up on you by being underneath one of the buttons. This was more of a problem in multiplayer games, where the camera zooms out only as far as necessary to fit both players on the screen. Of course, there aren't touch controls for the second player, but the learner could always add them. Set the buttons to 75% opacity.

Pushed another patch to make the buttons semitransparent.

Looks good to me! The color invertion can also be done by a simple fragment shader:
shader_type canvas_item;
void fragment() {
vec4 c = texture(TEXTURE, UV);
COLOR = vec4(1.0 - c.rgb, c.a);
}
I just tried it and it works. However swapping assets gives more control on the graphic design side.

I think using the inverted asset (rater than a shader) might also be a bit more self-explanatory for a learner, too. |
