Why only 1 star?

I actually like this game. Its fun. It could use some improvement, but I dig it - no pun intended.

Here is why Im hitting the rating with only one star: The Bonus Pack that you have to spend real money on! This wouldnt be too bad IF after doing so you start with more items at the beginning of every mine. BUT the items are expendable, and once gone, are gone for good. The game has been made so that getting three stars per mine is only possible if you buy a bonus pack per every mine or two. I dont like that kind of swindling and so my repayment is one star!
