Tap, Tap, and Tap!

Hello “One in a Trillion” I love your game❤️📱! But I have a few ideas for your game. First maybe add rare special versions of eggs named ✨glistening✨ eggs that can spawn, they’re basically like shinies from Pokemon, I feel like this could be really satisfying if you got one! Second, daily quests! These will add something more rewarding to playing every day! Third, Bounties! Bounties will happen every week or day, if you find the bounty egg you will get rewards… it will randomly pick an egg for you to get based on how far you are in the game. Thanks for reading 📖! And thanks for making this game!

There is a limit on everything you can collect

Gems and minigame eggs, which are super important for making progress, are bottleneck/timegated. You can only get so many a day and then you are cut off the rest of the day. You basically can’t do squat without gems because you need them for just about everything. If you are cut off then you might as well stop playing because you will never get anything done. At least with the minigame eggs you can add more stuff to them but there’s still a strict limit which stops you from enjoying the game once you hit it. I hate how almost every mobile game these days tries to dictate how much players are allowed to play the game, but will gladly let you pay to get more resources bypassing what you’d normally be able to get without paying. I’m not even kidding when I say this game would be one of the best mobile games ever made in human history if it wasn’t for that, if the limits were removed my review would instantly shoot up to 10 stars and I would start playing the game again. I just want to go back to the good old days when the developer wasn’t loony and the game was fun

loving it

used to play this game a while ago, lost the data, made a new account in 2024, stopped playing and now ive come back in 2026, this game is so fun and the base game is extremely simple once you understand it. either my memorys terrible, or i remember that there used to be upgrades or something, but maybe im just remembering wrong. this is a great game though, and i hope it reaches more people

Great updates!

I played this game a while ago, 1 or 2 years to be exact,and a lot has changed since then.unlike many other greedy games,only pushing out updates like a factory to boost revenue, one in a trillion’s updates have only improved and evolved the experience! I am sure that if I do stop playing and come back in a years time, it will only get better! 🤩❤️
