Well, you asked for more powerups and a harder game, so I present the second version of Defend Level 60 - harder than before, but with more powerups, including shields.
I hope you enjoy this! If you do, please recommend for Defense games collection.

EDIT: Daily 5th? Wow! I totally didn't expect this! This could be the beginning of something.
EDIT 2: I think some of you don't quite get the idea of the game - it is Newgrounds themed, so it needs Newgrounds graphics, otherwise it defeats the point of the game.
EDIT 3: A big thank you to all those who recommended this game for the defense games collection. This game is one of the most popular recommendations for that collection.
EDIT 4: OK, this is the last ever update I am doing to this. I've made sure that certain annoying levels (such as 28) appear less often and I have fixed a certain bug that not many of you would have known about. Also, I swapped one of the bgms for a better one. By now, I am sick to death of making improvements to this, so what you see now will have to do.
