I will reiterate what many others already have said. Kreds do not ruin this game and I enjoyed this game with out the use of kreds.
What this game lacks in a challenge compensates for it being original, cute, and fun. The concept of a monkey popping balloons is magnificent. And I do not mind this game getting more complex, but I do not want this game to get the point where it loses its charm and simplicity.
I am now going for the hard badges!
Everyone stop complaining; there is nothing wrong with wanting to make money. You can still ply the game and the extras are there for people if they want it. Always finding something to complain about.
"No badges!" "I hate Kreds"
Shape up!
