when you're placing the trees, dont snap them to the grid so they're not in straight lines like the 6 in the top left corner
i cant remember if you can turn the grid off with gamemaker but you can re-size it to a 1 pixel one lol
i have to agree with turning the contrast on the grass down, it looks good, but if the player is seeing it all the time when they're playing itll get annoying after a while
awesome progress though, really like it
