The shop is at the bottom of the screen. Buy mushrooms there and use the mouse to place them where you wish. If you change your mind and don't want to buy a mushroom, press space.
~Credits~ This project is based on Mushroom Farm Defender, a real game you . can find on the internet. Thank you to @Turkey3, @EvilCookie36 and @ErnieParke for helping me with scripting! ~Notes~ This game is nowhere NEAR completion. I am always working on it to . improve and update it. Most of the sprites are in a "placeholder" state and are not in their final look. Also, some numbers in the script like the amount of money . you get from defeating the enemies may change later. ~Update log~ Sunday, June 30th, 2014 A.D.
