Lower Daily timer to 22 or 23 hours. A lot of games do this so that people will still be able to get it even if they last used it really late (like on a weekend).
Falling... surfboard - sweet, just in time - surfing - wave ramp up into bat - fall into rope - trip into wave - fish ATTACK - SAVED - jump into bat - fall into rope - trip into wave - no fish ATTACK
After upgrading the mini drones, in the how ever many hours I have been burning playing this game, I only saw one spawn with more than 15 hp and they never did damage to the heroes with 1 or more armor.
kinda looks like some levels don't always spawn creatures - haven't figured out if it's intentional or not - occasionally maybe 1 or 2 will spawn right before a round is up
Some global people promotion buttons would be nice - select a worker and two buttons would be available instead of one - promote worker and promote all workers
This doesn't make sense - can't set units to defend while hero retreats because most of them are faster than him. If I set them to attack, they wait behind the hero until someone comes in range which is rare because the hero runs forward to attack when they get in his range. I spend most of my mana healing the hero while EVERYONE retreats.
The walkthrough sucks - I'm stuck on 25 and then watching the walkthrough, every level is shown with what appears to be the most effective ammo - most of which I don't have.
I think a Genetic Affinity would be a nice addition. Basically, if you keep breeding creatures with the same appendage, say horns, and if the horns are on the offspring, it will give a natural bonus to keeping the genetic trait. So, continuously breeding two creatures with horns, after 5 generations the offspring could have a +25% towards the creature that has horns.
You should make a Fantastic Racer, similar design to this but the fastest time to get to the finish line (over obstacles and such). Allow uploaded ideas so others can race a ghost vehicle down the track.
