Since the new update added fire, why not have ice?
Instead of ice breath, what about an ice ball? You would still cough up the ball, but where it lands it creates a ring, and all enemies in the ring have ice spikes come from the ground and stab them.
What about thin ice that shatters shortly after you step on it and ice water that destroys your robot's circuts?
Yea I think so too
I also think there should be different tiers of elements.
Fire > Magma > Scorching
Ice > Frost > Glacier
Each new tier being a harder version of the previous.
