Agree with @eshshual, MAX (or x1000) button wouldd be nice. Also, maybe let players turn off floating achievement icons? i can't see how much money i have one minute after creating new city (50 achievement icons above money counter), so i need to wait to see current money.
The first 2 minutes after reset, if you are level 5-6 or more, it doesnt really matter what you buy. Just buy all and forget about money. You can fix it in the next 1-2 minutes when your income will be stabilized. :)
Game is good: cool graphics, simple, but interesting gameplay. 5/5 Also: Level 11 needs 4 or less turns to 3-star, but it's easy to pass it in 2 turns :P
