Press the arrow in the corner to open the shop, and buy turrets from there. Press the play button and watch as your turrets shoot down the enemies! Click on a turret to view it's upgrades and range. Note: If a turret is shooting out of it's range, that just means it's range is too big for the circle to comprehend.
This is a version of Crazy Tower Defense, but educational! There is a math question (on average) every two waves, and answering the question right grants bonus money! But getting it wrong will cost you...literally. You'll only get like 5 bucks. If you see any enemies but they die so quickly you have no idea what they do, comment below and I'll try to let you know!
