Sometimes small details like this seem to visually get stuck in my mind even if I see/read them long ago. I think it mostly happens about things that I am interested in. Like games, art and music.

Yup! It used to be called Colonies and I've been developing it this whole time! I cant believe you recognized it :)

wow!
I really love it, and i want to play it!
 

I remember seeing the game on IndieDB long time ago.

If I am not mistaken it went under a name change as well (colonies?).

I like this look. Fits to the game's feel.

No it's no sarcasm.
I don't know how to use it.

Is that sarcasm? The trees are in no way big.

Those are pretty big trees.
