It's a bit buggy too.
1.) I completed the small Legion, but i didnt get the badge
2.) I quit the game right after starting and got the "Die in 10 seconds" - badge
3.) Getting a "Double Shot" Power up while having a "Tripple Shot" one makes the Tripple Shot last longer
And, what the hell are those blue cells :p
One time they took all my Elements in one round, but still it wasn't game over. I had "Double Dare" actived and even got it awarded.
Then i think it really sucks, that my towers don't attack the first creep. Several times one came through with 1% of it's HP.
