Amazingly fun!

I downloaded the app when it came out. And when the updates started to roll out it became a lot more fun! Now my friends are getting it and trying to beat my high score!

Fun game with beautiful design

This is and extremely well done endless runner. And I’m not a fan of many endless runners. Clearly a lot of effort was put into this game. It’s extremely playable and fun. And the design and graphics are beautiful. Also if they designed any shirts or stickers I would definitely buy them. I highly recommend it. Well done!
Update: what the hell, ads!
Been playing for months and now an ad pops up. Shame on you!

Great Game with Serious a Flaw

I love this game. The design is great. The play is quick and entertaining. Recently the game has begun to erase players diamonds. Diamonds are earned in game or purchased in order to upgrade your whale. Over the past month my diamond supply has been reduced to zero about every third time opening the game. 2800 diamonds erased one time. 1300 erased the next. It has become impossible to save enough diamonds to buy the needed upgrades for the harder levels. Extremely frustrating. If they fixed this issue I would easily rate this game better.
