App not opening

The app won’t open on iOS 27. Clicking the app to open and it flashes black for a second and goes back to the Home Screen.

Crashes

Newest update just crashes and never opens

Issue

There is no way to disable the auto buy once you unlock them( at least that I can find )so the atom generator outspends the matter making it impossible to have all generators running at once to progress

Response from developer

Thank you for your Report! That is actually not intended. In the upcoming Update (2.2.3) you will be able to stop the Auto-Buyers individually or all together. If you got more problems with the Game, don't hesitate to contact us: info@netbyte.bz

Unplayable

Add banner covers menu- cannot move or close, so game is unplayable.

Response from developer

Thanks for your feedback, and sorry about the issue! The problem with the ad banner covering the game menu has been fixed in update 2.1.1. Please update to the latest version. Thanks for bringing this to our attention! If you get into another Issue, don't hesitate to contact us: info@netbyte.bz

Good!

I really like the concept and execution of this game. It's really fun and I love incremental/idle games like this! Keep working on it, it's really good!🙂 (I usually don't use emojis, so that means I really like this game if I use an emoji like that one.)

Response from developer
