I disagree with the planks floating in air.  They could have undersupport from the post nearby. In my opinion is shows the dispair that the wharf is in since even the extra supports have started to give way.  Although, stepping on it would probably collapse i still think its a good effect.

This is an amazing piece of work.   Your cave, this grassland, I can't wait to see what other high quality works you produce.  You very well may inspire me into doing some adventure/rpg !

Edit:

  I didn't realize that Flare was a OSS RPG! Very cool!
