I used to play this a few years ago, and decided to download it again. Now, I can't sign into my old account, fight the wildebeast, or participate in the Survival of the Fittest competitions; comes up with a connection error on all those. I can still watch ads though. Guess the connection is fine for those. Annoying.

2025 Update: Still playing this game! I no longer have the subscription, but if I had the money I would buy it again. This game runs so smooth, doesn't eat up battery, has consistent updates and events, and adorable tiny crabs. Competitions are always optional, there's long term and short term goals to reach, items to collect, and a touch of customization. A very relaxing and well rounded game, and ads are always rewarded and never intrusive. Thank you!

Very addicting. I've sunk quite a bit of time into this game. Once you unlock all the upgrades and mutations, that's pretty much it. There are weekly tournaments and other things to try and get if you're a completionist, but I'm quite bored with the game now. I started playing the game a few years ago and stopped for quite a few years. In that time, nothing has changed. It's still just a mindless march to infinity until you prestige and begin the mindless march again.
