When I updated the game to the newest version all the data I had previously saved was erased and I pretty much had almost everything unlocked at that point and maybe had maybe a few things left to get and because of the update all the progress was deleted I just wish you had an option to toggle the old way of playing the game off where you use emeralds to buy items and get multipliers to get emeralds to get the next item honestly that was a really good feature and what sucks about everything is I have a really shitty memory so crafting the items required to get everything is kind of difficult due to the fact that I have to constantly keep looking back maybe 10 or 11 times to try to remember each recipe and item to go in the recipe
