Drain Defense 0.46

Early functional prototype of a fluid based tower defense game. Avoid letting the vulgar objects down the drain! You have 30 lives, your only objective is to "stabilize" the map, in other words get to the point where you cant lose! Land! Youll need some if you want to build towers on water. Notice: the upgrade button does nothing atm This game is open to collaboration! Please see https://godotforums.org/d/33142-drain-defense-playable-and-open-to-collaboration.
