unfortunately, the minimum required Android version is 2.3 alias Gingerbread. We needed to change this from the previous minimum 2.2 (which was prevalent until V-Play release 0.9.4) to also support the new Android 4 versions. These already take up more than 25% regarding the Android documentation: http://developer.android.com/about/dashboards/index.html
On this link you can also see, that the Android 2.2 and below distribution equals 16%. Skipping to version 2.3 also made sense, because generally with version 2.3 above the Android devices are more recent devices and are guaranteed to run V-Play games with high performance. As a possible solution for your problem, you might upgrade your HTC Magic to 2.3 with these instructions to run the game on it: http://www.allroundgeek.com/2011/07/upgrade-your-htc-magic-to-android-23.html
However, since your device is already more than 3 years old, performance may not be ideal on the device as the CPU and GPU power of the Android devices improved quickly in the previous years.
Regarding the download issue:
I just tried downloading one of our test builds from the build server to an Android Huawei Ascend G300 with Android 2.3 on it, and the download worked fine. Are you able to download other files from the web with your Android device browser? I am using the Dolphin Browser and QR Droid for scanning the Android downloadlink QR code – maybe you could try the download process with these applications?
