So after a near fail on level 28 (made it with 1 minute to spare) I made sure I saved up heaps of cash before attempting the last two levels. Needn't have bothered though, levels 29 & 30 were both really easy, the items were available in usershops and cost 4,000mp and 28,000mp resepectively. I wonder if everyone finds it this easy or was I just lucky?
