Ruined by high IAP prices

I loved the original game - this is an excellent follow-up title - but the prices for IAP are WAY too high. If I want to start getting my hands on new levels, short of grinding obsessively for hours every day, I need to spend $6 on a track pack?!? I would gladly pay $5 for the whole game - but if I bought every piece of IAP, this would be a $40 mobile title. Ridiculous. Excellent game - would be 5 star review if I wasnt being bilked.
