I'd like to see this in future games: armor creator/mixer. you create/mix armor (mixing gives stats from each) and it shows you what it's stats are. this would rule
this needs a difficulty setting (easy: high % of swans, low % of planes, tight "V" Hard: low % of swans, high % of planes, wide"V") and also more upgrades, a save button, and most importantly, LESS PLANES!!!!!! I barely have enough room to get through them myself, let alone my whole flock!!!!!!
idea for 4th: a madman is trying to make the ultimate weapon, and finds the remains of Jack, the half-dead Giant Squid, the remains of the Desert Tank, the half-dead Three Headed Dragon, and the passed-out Mammoth. He experiments on them and makes a fusion of them. (final boss). also, mini-areas that are unlocked every ten medals and have treasure and a miniboss that guards AWESOME equipment. for first miniboss: Megaslime. large green center, three small blues around it, three small reds around it, the blues and reds have magnets in them, a lightning rod in the green, and a magnet on top of the lightning rod. + if you think this is a good idea.
how the hell does a "very easy" guy do TWENTY ONE DAMAGE??? and how does an attack go through armor? IT DOESN'T!!!! make this WAY more realistic. I'd rate this 0/5 if I could
tips in case a second is made: multiplayer! I don't mean head-to-head, but to work together. my friend and I love this game, but we want to play it together. also, make special towers. after you place them, there should be an upgrade. same for units (ant->fire ant, spider->cobweb spider)keep this comment alive!
