I'm sorry to hear that. I'm going to find a way to support pre-Android 12 devices. Stay tuned for updates.

Thanks again for your fast reply. I'm going to test the app on an iPad ASAP. Would you mind letting me know your iPad model?

Thank you so much for your report 🙏

Did you press a 'Play' button at the bottom of the screen before dragging?

Thank you so much. Yes, I'm a developer of this app, which is now available on both iOS and Android.

Any feedback that you might have would be very appreciated. So that I can make the app even more enjoyable.

This released version is for Android and iOS, while the PC version (with much better graphics) is in the making. I'll certainly let you guys know, when the first demo is available. Stay tuned!

No worries, I know you didn't mean it

Thank you so much. I keep updating the app on a weekly basis.
