Great game, but there is a crippling bug

I was so happy to find this amazing game on the App Store. Its probably the best Tower Defense game out there, but there is a crippling glitch/bug...I cant pass the second level; the game is unplayable. Can you please fix this, there are most likely more people out there that are just as bummed as me because of this fatal glitch/bug.
