This game is amazing! The first hard badge could have been considered a medium for me. Here's what I did (I had 11 def and 11 speed, no rotation and about...6 allies): Simply gather momentum and then hold down the mouse button FOREVER. Let your allies FLY! They will break off, create even more smaller bits and kill even more ships. If you see a "more ally" powerup come, get it, and then release your mouse button for a second, then hold it again. This is to allow your new ally to gain momentum. Your job is to go through all four corners of the screen, to kill as many ships as possible. Get hit by ALL the red mines if possible, and avoid the blue ones AT ALL COST. I got killed via the blue one, with my health at 300+ brought down to about 50+ just by hitting one. For the green one, stay away from it, one of your allies will hit it soon due to the fact that there would be a lot of them.
Hint: If you're going to place the ball at a corner, try "teleporting", at the side, move your mouse off the game and near another side of the game (but not inside the game), if a ball goes too near, move your mouse into the game to shift your ball away. This can also be used in normal playing.
The game was great, and it kept me playing till level 28, where it got boring due to the constant sameness of the game, and I only played the last 4 levels just for the hard badge.
This took really long to load. And I mean really. I went to armor games and played 3 arenas on BTA and it wasn't even half loaded! While I understand if it really was a big game it would take really long, but this long? So I went and played 5 more arenas and it was about 90% loaded. That's when BTA started lagging. So I stopped and waited for the rest. So the waiting time couldn't be considered THAT long since I played a few games while it was loading and time passed quickly. So here's a thought: while waiting for the game to load, go and play another game :)
Got bored pretty fast...and rampage caused the AI to keep on aiming at those near the top, causing those below to attack me even if I spelled those words at the bottom, therefore I was forced to spam letters using both fingers...and that cleared the field :)
I went to the "top rated" tab and I found this game instead of Sonny/Gemcraft. There I found one challenge I didn't see yesterday, yet here it ended in 22 minutes.
Got the all avatars at first try, then the 50K at third. The 50K is more on luck, so if you don't get it the first time, try again. Why the high rating? 3/5
