Ok after finishing this game with evey hero here is my thought again.
The aiming stays as it is! :D no but really youre getting the clue pretty fast and at the and i easily hit even those small green basterds with perseus (which is the hardest to aim in my opinion) For all thos aiming sucks not 5/5 voters. Play it with heracles the first time. buy the bounce upgrade no aiming needed no more still youre getting more and more clue about how it works and you will be able to play it with the other 2 heroes without problems. Just a tip. Be sure to also get the first blood xp on every level. Its easy to achieve especialle with heracles. So this game is a 5/5 to me!
Improve the aiming get rid of the hero restriction and this sure has got a chance to win weekly or even monthly! I personally really like this kind of games.
