Played this game for a long time, and the gameplay is fun, however:
1) they have had multiple buggy updates 2) you will never get all of the items, nor do the developers help you get all of the items 3) you will tire of this game quickly 4) you think you are progressing, but you arent, the game has the word infinity in it for a reason 5) your best bet is to play it for a couple of months, and then delete it from your device. You can do all the neat things in a month or two, then its over. No more fun things. Just endless, meaningless upgrades to items. 6) the gems and potions seem cool, to make you more powerful, but the upgrade patterns arent consistent, and quite ridiculous. 7) you have other choices for games to spend money on, dont waste money on additional in-game purchases with this one.
