This is my take on Warframe's youtube video, "How to Make a Tower Defense Game. Currently, there are 7 maps to choose and play from, 30 waves, as well as 6 turrets in the shop. Press the play button in the top left to start waves, and to buy a turret, click the arrow in the top right to open the shop, then click a turret to buy it. Once you have bought your turret, you can move your mouse over onto free space, and click again to place the turret. If you buy the wrong turret without placing it- no worries! Just move your mouse to the bottom left trash can and click to remove the turret and regain any money lost.
Thank you to Warframe and his youtube channel, this was created and modified with his "How To Make a Tower Defense Game in Scratch". https://scratch.mit.edu/projects/636448468
