My first tower defense game. Currently only has 15 levels. If there's no sound, press options at the main menu and slide the volume slider. How To Play: The unit that costs 25 is a basic shooter tower that shoots every ~1 sec. The unit that costs 40 is a generator that gives you 5 every ~5 sec. The unit that costs 100 is an advanced tower that deals more damage than the basic shooter tower and penetrates through enemies, but shoots at ~2 sec intervals instead. Finally, the unit that costs 60 is a wall that can withstand ~40 hits from the weakest enemy.
