It certainly has been quite an adventure, but the Android version has been officially released! Well, it’s still in the “open testing” (or “Early Access”) phase, but it will be moved to “production” within the next few days. You can download it here: https://play.google.com/store/apps/details?id=com.betacomsa.CIU.ia 5
Sadly, Google Play only supports 64-bit apps and will flatly reject 32-bit code, so you may find that your device can’t install the game. This includes some devices which have 64-bit hardware but have a 32-bit OS installed (this can happen if you have a low- or medium-tier device with less than 4GB of RAM).
Oh, and yet more anti-cheat measures. Because cheaters will cheat.
An update for iOS has also been pushed to Apple’s App Store. It’s unclear how long you have to wait until it’s available for download world-wide. Report your experiences here.
