Good game, but I dislike the fact that when you leave a bee in a mutation square, it continues to mutate to the point where it starts hindering everything.
The trick to this game: you can stop any creeper node from producing creeper by pimping out your energy collection, building 6-8 blasters, pausing the game, and moving all of them on top of the node. Once you do, the creeper will dissolve and you can quickly build relays to your blasters. Then you can them back to use on another node, leaving one to hold it down. Also: for the last level, move the city up to the rim of the bowl, build 2 collectors at a time, and then build 3 mortars around your base.
go ahead young padawans, complain about brass items all you want. just remember that without them, you wouldnt be playing this game. flip is a real person too.
i never liked top scrollers like this until the first enigmata came out. this game makes the first one look like crap. definitely the top of its class.
