In-app purchases: $0.99/lvl

Fun to play for five minutes until you beat the first two levels. Then to keep playing and to unlock more than 3 planes you must pay to contine. No way. This app would only earn 3 or 4 stars even if the content werent so expensive, since it is worse than the original (graphics look awfully pixellated among other things).
