snow piles too wide

Thanks for the nice package.

I have the problem, that the snow piles are too wide, so that the image (house, trees) get distorted once snow piles have accumulated.

This is my usage:

```
(set-face-attribute 'snow-flake nil :font "DejaVu Sans Mono-11")
M-x snow RET
```

Is there a possibility to use the nice pile glyphs without distorting the picture?

I am on GNU Emacs 30.0.50
