Hey great game.
Content wise, I would appriciate a bit more information "guidance" to start more efficiently. 

Error wise: I saw that the mouse-wheel clicks the plant - not sure if intended. and that when I have 6 click power but 1 energy, it consumes the 1 energy and gives 6 minerals. Tho usually it consumes 6 energy.
Oh and you need minerals to pay for upgrades and money, but you can only sell ALL minerals in one cathegory. I would appriciate an option to sell a portion of the minerals.
