Elemental Incoming

A simple idea with an increasing level of difficulty. 

Perfect for ETLHTM (Easy to learn, Hard to master)

The better you do the more enemies will come. 

Match the correct bullet type (Fire, Water, Earth) with the correct enemy type to kill them. 

But be CAREFUL, an incorrect choice could either do nothing, or backfire.

See how far you can get and see how accurate you can be!

Good luck!
