I haven't played in about a year, but decided to play again recently. Im sorry to say that the game is not fun anymore. I used to love it and would play it for hours on end, but after the new update it has become boring. I loved having in game money that I could spend to get luck sauce. The fact that they changed it to gems annoys me, especially because all that money I saved up went to waste. It feels so lifeless now and I don't get that rewarding feeling when I find a new egg anymore.

From 5 to 0 stars. It used to be a fun and challenging game for a collector game and how everything was before was perfect but with this new update it requires you to have so many more resources that it just feels like a ploy for money. It possible could not be but with how it feels for me it just feels like they're trying to get you to pay them more money.

Left a simple review earlier, decided to revise it. This is pretty much the perfect game. There are no ads at all, and the gameplay is quick and not buggy. You can play it offline. It doesn't take up much space, less than 100mb! You can take it slow or go fast, and there are a bunch of minigames in it. There is also a competitive feature. Very fun and very underrated! bart_rathbone
