GigaD: The Dragon has a minimum range on its gun; if another bot, say your Shield, is within that range, then the Dragon isn't allowed by the game's programming to shoot at it.
The challenges annoyed me, but everything difficult does, and they're supposed to be challenging challenges. A good game, fairly unique.
WALKTHROUGH:
To start with, if you group the tombstones in one place, you get -mega awesome xp-. Get as many as you can together -- unless there's one all the way across the terrain, then leave it alone, because that wastes too much time.
Next, attack the pile of stones, trying to keep it near the middle. Attack The Beard too, running away when necessary to dodge his attacks. When you get to axe level, you can attack him a bit more (say when you've been chased away from your stones for a moment), when you're maxed out ignore the tombstones completely and attack him whenever possible.
TO DODGE Basic attack
{This is the one where he sticks his tongue out.}
Run a short distance-- or if you're on the left side as I commonly find myself, get him to chase you so he's underground and you become immune to this while he stays there.
TO DODGE Windmill Attack
{This is the one where his mustache spins.}
Attack him once while he's still charging it, then run as fast as you can. Cannot be immunized, and the Basic immunization makes it hard to see the Windmill.
TO DODGE Eye-beams
{This is the one where he shoots red lasers out of his eyes.)
Go to the very edge of the screen while he's firing on the top of the screen -- the side that he's on. When he comes down, attack him once driving him away from the side, move back to the edge, then pound him while his lasers are going off. To immunize safer, run to the side, then jump onto either higher island when the top lasers stop.
TO DODGE Bread Attack
{This is the one where he hides and loaves of bread fall down.}
Hide underneath a floating island. When you see them drop, check if there's one directly above you, and move out from under it. Easy, just time consuming.
TO DODGE Epic Fireball Attack
{This is the one that... you'll know when you see it.}
This attack loops; left-right-middle-repeat. On the left side, there's a point just to his right and below him where you can continually attack him while he uses his attack. Middle and right, just run away. Cannot be immunized.
I love text adventures!
… Except for this one. More then five sixths of the normal commands are not accepted. It's ridiculous.
And the tutorial=sux :/ Tells you nothing.
