Calm down folks, as stated, it's a Demo with link to Buy the full version. Only has Colts vs. Saints, and only lets you play one 3 minute quarter.
If you don't want to flash with recovery, you can download and extract the "sdcard" folder and the apk, and just copy them to your sd card, then install the apk as normal.
FYI it works fantastic on my Epic!!
Not so much on an EVO
