Dialogue
Intro
(Crazy Dave and Penny appear)
Crazy Dave: Woah! Where are we? I feel like I'll be blown away!
Penny: Data shows that we are 11045 meters from the ground.
Penny: Maybe we can find something special here.
Crazy Dave: I have acrophobia! Ahhhh! I need to get inside. We won't find anything way up here anyway.
Penny: My detector shows the opposite. (Crazy Dave and Penny leave)
Tutorial (old)
Crazy Dave: Only flying plants can be planted at the open sky outside of the deck.
Crazy Dave: When being attacked, the durability of the ship will decrease. You lose when the durability runs out, so protect the ship.
Strategies
The main gimmick of Sky City is completely different from other worlds. This change may give players difficulty. Zombies also come in quickly in Sky City. Rotobaga is given to the player, which can be used to defeat early zombies.
In hard mode, the player has to defeat leveled-up zombies.
Strategies
Zombies in Hard Mode are at Level 3, which can be difficult to deal with. The Rotobaga provided will do almost nothing unless upgraded. A better choice would be Asparagus (the game levels it up for you as you get stars.)
The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost lane.
