No bonuses for memory pieces?

Hi Chicken Slayer,

I'm with Jenny in frustration.  I have spent countless money trying to collect memory pieces and beating levels.  And with memory pieces, have been stock piling as revealing puzzles does absolutely nothing in gaining bonus rewards.  Originally found out collecting memory pieces was a test pilot with certain players selected for this challenge, but to date, nothing has changed in rewards for memory pieces collected.  How disappointing!  Also, this new golden pin challenge is useless in not providing bonus rewards on successful completion of level in first attempt.  Another disapointment!  I've questioned both these challenges to Care King on the point of these two challenges, with no reply from a team member yet.  Another disappointment!  Reaching Bubblegum throne at 5 levels with one life constantly to only receive 1-3 gold bars is uneventful.  Another disappointment!  I am just going to stop spending money on this game until the game starts paying out worthy bonus rewards that substantiate challenges completed.  Not to collect memory pieces and be rewarded nothing!  Not to win golden pin levels and be rewarded nothing!  Again frustrating and disappointing.
