I love everything about this game. So excited it has been released on Kongregate! I can see the hard work put into this game, all the features, leveling systems, new towers, it's true brilliance.
For all of those telling them to hurry up on the next series: Do you want 30 levels? Look at the quality, and time put into making this game, truly remarkable. You can track their process at their blog... I really look forward to the next of the GemCraft series.. the story line, crafting, everything. True brilliance.
You need to shoot it ('F' key) to make it shrink and then you can go over it :)
