Hello, I believe the admin knows me on Facebook.. So I reply it here what I wrote on Element Tower Defense Facebook Page.
Well, My suggestions is, level 3 Triples... Or quadruple elements tower..
Or
My tower is a cold cryo shooting tower that damage and slow everything in a radius..
And
Gunpowder tower change to sniper tower which is high damage but slow..
And
Gravity tower that cast gravitation to a creep that stop it for some seconds and damage it when it drops..
And
A tower that can warp...
And
A tower that can deploy mine for some percent..
And
Change the Electricity tower bounce to multi shots cause bounce is lagging and over ratted..
And
Change the periodic element td attack type to lucust swam that have 6 swams of the 6 elements..
