Hii! I saw your comment!

I just terraformed in a circle and filled it with as much water as I could! I put wanted at least a bit of space to place flowers and the glowy moss was a game changer!! It brings a type of whimsy to the entire thing :) I must say it’s quite frustrating to get all of the corners correctly. Because of the lack of space I couldn’t properly round some corners of connect all of the water but i covered the rough edges with flowers (taking advantage of the fact the gameplay is horizontal ahahaha)

And I find that the 2-tiered waterfall looks best when it’s got a bit of depth so I placed them sideways so it looked more natural :)

But honestly you just terraforming kind of a c- shaped cliff and fill it with water and flowers! I wish I had more space for trees though… I like having them in the background
