Please never Nerf this game. I love the challenging aspect of this game. It took me 10 to 15 times to get 3 stars in 2-4 stage. I kept trying and trying and it's rewarding to know your efforts really paid off. Please add more gear items, upgrades and hero abilities and newer stages and more events and rewards. It's been a while since I came across a game which can challenge my gamer instincts and skills. Don't listen to those noobs who always complain about challenge and difficulty. I love this game, but heard that the level 2-4 was almost impossible, sooo, as any gamer should, I decided to make may way up to that level expecting it to be extremely difficult, but instead it was extremely easy... People have also said it took them 10-20 tries... I got it in my first, unless you're very bad at video games it's really easy.
