1. Click the large button on the top-right to choose a map. 2. Buy towers from the left panel and place them on the field. Cancel tower placement with [X] key, or click back in the side bar. 3. Press the "Start" button at the bottom-left (or [space]) and watch the enemies get attacked until the wave ends. >> If you need money fast, click "SELL", and select the tower that you want to sell for half price. Note that towers can only be removed while there are no enemies, so plan ahead before starting the next wave. >> Each tower has strengths and weaknesses. You might think they are weak if used badly or overpowered if you figure out their strengths. Think about how they function and place them where they make sense. >> Try to survive 20 waves without dying! (The game works on mobile!) Extra tip: Tap [i] to see the total money spent for all towers. Halve it, and that is what you can get refunded through selling.
