Really Good, but......

It was easy to play and i was really enjoying the game until I got up to stage 100. That freaking two dragon head boss is just IMPOSSIBLE to kill.
And it pissed me off so much I actually punched a wall. The heads weakness is pretty easy to hit at first but as the head start to move, it gets harder.
Then the weakness moves to their neck, and If u dont have like LITERALLY 100% accuracy its like impossible to hit. And those minion dinosaurs attack in groups of 10 and I have to hit them like 8 times to kill them even though I have maxed my arrow power. And while Im trying to kill the mini dinosaurs, the boss attack like HELL. And I when try to hit the energy spheres the boss spits out, these electric spheres block EVERY one of my arrows. And the spheres lower my castle hp like 1000 each time.
Im just MAD right now...
This is actually the first app game that pissed me off this much. Just make the game difficulty less hard, pleaseeee!!! Make the dragon one head and remove the electric spheres. Also, the castle hp upgrade is too expensive.
