My confession: I had not seen the content of that thread cause of the title for quite some time xD
Had always thought it was "just" recolors and therefore nearly missed one of the best tree selections out there^^'
Added some cliffs / walls / roofs to the tilesheet and am currently working on roof objects to make them prettier and more variable. And of course, windows and doors that fit to the game's style.
I also adjusted the grass color but i have some issues with my display, so if it looks weird, please let me know
