For OGAM28

Controls: 

• Left click to place selected material
• Scroll to switch material

Features:

There are a handful of materials/objects that can be placed

• Glass: This hovers in the air and is your best building tool.
  
• Water: Simple, refreshing, H2O. 
  
• Sand: A nice base that is heavier than water and can not be passed through.
  
• Fish: This consumes oxygen and swims around. Be careful, it will die if it has no O2 or water!
• Eraser: This will delete any objects you place.
• Water Generator: This can help automate your base when the next item consumes all the water. It automatically places water over time.
• Grass: This grows, consumes water, and consumes carbon dioxide. It will die after a while if it doesn't get either of the needs.

The downloadable version may run better if the browser version runs poorly
