WIP Puzzle Game for mobile

Hello!
Art is the hardest thing for a programmer. I am a programmer :slight_smile:
I am looking for some feedback on the art of a mobile game I am working on.
Since I was the artist, dev, designer only way to add variety to the art was procedurally changing it’s look.
So I decided to opt for a simple 2D day night cycle to add more life to the background.

Here are some screenshots of the game in different times of day.

What do you think about the background and the foreground (board)?
Any kind of feedback will be really helpful.

Thank you!

Looks simple and elegant. Nice work.
It looks very ‘2D’ but I don’t think that is bad, it is a style that is clean and acceptable especially on puzzle games.
