Have you considered having each achievement multiply the multiplier by 1.05, or some other amount, instead of increasing it by a fixed amount. It would help with balancing out the value of achievements later on in the game.
i want to play this game but when i go to start it says to click play in the lower right corner... tis button does not exist :( 1/5 untill this is fixed
PM any details - did you buy any? Any idea how many, if so? We'll get to the bottom of this.
