A pet egg with wings that can fly at over 150 MPH and destroy everything from kids in cardboard boxes to complex rockets? Yea, I had one of those back in my days aswell...
A few friendly suggestions:
1) A simple and short user-friendly tutorial that pops up once player starts the game
2) More consumables (Health potions, strenght/agility/intellect potions, maybe even a "more gold per enemy" potion).
3) More crafting options (unique equipment, maybe potions too).
4) More equipment in shop which is randomly generated every 10 minutes or so.
5) Rolling over on attack skill shows detailed information about it (DMG, CD).
6) Chance to encounter random things like treasures or goblin merchant.
Seems like someone has NO F***ING CLUE what MMO stands for. @a3lex, anachro: There's difference between honest failures and obvious trolls. There are many devs (including me) that don't posses awesome coding skills, yet we don't post fake tutorials with 0 helpful content. He's doing this for the money, cause the more plays the game has, the more money it earns. Such retards should be banned + jailed.
This is one of the most F-ing amazing games I've seen on Kongregate. And still some retards do 1/5 for no mute button or just because they never played a real piano and suck alot. IMO, this should be a featured game, not burried somewhere deep in "this-is-not-armorgame-game-so-let-s-rate-it-1/5-!!!!!!!" section.
This game is not all about teamwork. You must have strategy and think new tactics: If you are shouty and about to die - shoot some tank with missle and mortar then reload and repeat. No matter if you die because your teammates will have better chances of destroying towers/tanks. Anyway if you want more tanks - go to CC's site. They also have tournaments there so you can test your skills. This game is good as it is now. All other stuff would mess the whole game and make it less fun.
