Good game but needs fine tuning

I love all monkey bloons related games. Ive been playing this one for over a year now and its good, obviously Im still playing it, but there are a few things about it that drive me crazy. They need to calibrate the value of gems, ie/ spending 5 gems on a supply crate (valued around 1000 bananas), or you could spend 10 gems and get a bonus monkey (valued usually 400 bananas). Thats just one example. My other complaint is that the tracks are too repetitive. Other than that, its still a challenging game and I hope it gets a much needed polishing in future updates.
