Ideas
(1)Saves for level design (2) Online play (3) as spicypeanuts says, more elements/building blocks such as owner only doors, renforced wood blocks (more health), metal blocks (indestructable), and more cannons (4) More powerups would also be nice
I want to be able to make our own packs for energy and people could up or down vote (3 highest voted would get on featured page, 3 lowest would get taken off and refunded but you wont be able to make another for a while)
