Great in the beginning, annoying later on

I used to enjoy this game very much, but now at advanced levels (Im currently at level 34) its rather boring, sadly.
You need tons of xp but dont have many options left to get them :-(
Building doesnt really work since there are not many buildings left (like, only the 30th Dart Monkey).
Spending lots of money on decorations (e.g. buying the 5th monkey wizard) doesnt gain you a single point of xp :-(
I cant even remember when there was the last mission issued by the king :-(
Sadly, you still cannot really play the game without internet connection - try playing for 3 days (i.e. 72h) to get a building finished...
And now this Banana Guy would be a rather welcome addition - I was really looking forward to having a new monkey, building some new buildings, getting xp for them and maybe even having to save up for them, be it bloonstones or a huge amount of cash. But no, you have to pay for it with real money, theres no possible alternative :(
Really sad. :-(
Paying real money should only be the easier option, not the only one!!
