Found a bug, when running two doctor towers occasionally one of them will stop healing altogether. I've found that moving them around in the tower lineup reactivates him. Also, not really a bug but is annoying, when the message pops up during a round for collecting one of the unlock tokens the keyboard controls become unresponsive requiring clicking on screen to fix.
I am loving this game. What would be really useful would be a calculated spell recharge time on the toolbar for each spell so I know how long of a cooldown I'll have before I use a specific spell.
The order you set the explosives is the order in which they will detonate.
You can switch the type of explosive to set by clicking the corresponding button in the lower left corner.
Unwavering Achievement:
Pecking order:
Black Swan>Trumpeter Swan>Mockingbird
Max out all three of the birds' traits (Seraphin Wings and Hippocampus last if you don't have the points).
Play Endless City and immediately wipe out your flock, triggering Apollo's Phoenix. This will be easier if you avoid growing your flock at first. Then collect as many birds as possible while focusing on keeping ONLY your leader alive. Bloodlines will make your Trumpeter Swans invincible; all other birds you can afford to lose. Mockingbirds that die will trigger Mimickery: Swansong II, giving you even more Swans. Soon you'll be flying an entire flock of invincible Swans led by a Black Swan. Fly your Black Swan in the middle of the screen to anticipate planes from all directions. Keep dodging and collecting birds and you'll get the achievement in no time.
