Dog option

[Wiljami]

There should be an option where the demons are replaced by dogs and the packet by a ball. The dogs should then chase after the ball as it moves across the screen.

There is already an unofficial fork that had dogs. That kind of visuals should be implemented in this repo too.

The current visualization is really dark and maybe scary. A more friendly-looking one should be implemented and dogs and balls would work well.

Can we also add barking sound effects? Those would lighten up the game and give better feedback to the user of what's going on.

@Wiljami that's outside the scope of this issue. When planning the next major release, such features should be considered. 👍

Reopening because this issue is now relevant. There's something wrong with the dogs as they don't follow the ball.
