 Flowers can only grow (well) in certain climates based on two properties: humidity and temperature. Watch out for existing vegetation to get an idea how humid the land is and check the appearance of the tile to see how hot it is. When well placed your planted flower will spread soon but an odd choice might kill your flower almost instantly. So choose carefully. When the flower spread significantly you can dig up flowers again to collect more money.
 
 **Controls:**
- - H: Selects shovel
+ - D: Selects shovel
  - R: Selects research
  - Spacebar: pauses game
  - 1: runs game at normal speed
  - 2: runs game extra fast
  - Mouse wheel or plus/minus: zooms landscape
- - W, A, S, D keys or CTRL + left mouse button or middle mouse button: pans landscape
+ - CTRL + left mouse button or middle mouse button: pans landscape
-
-** On screen **
-On the left side of the playing screen you'll find several buttons:
-- Settings: disabled.
-- Save: saves the game instantly, only single slot.
-- Load: loads previously saved game instantly.
-- New: starts a new game with a different terrain.
-- Information: shows the intro/information screen (again, also accessible with the Escape key).
 
 Have fun playing!
