Okay. Can you explain what you're doing to install it? Are you sideloading the APK from another machine or are you downloading it via Humble's store directly to your device?
Does the game run at all or are you not getting into it at all?
I tried downloading APK from humblebundle.com and i tried via humble's store app on tablet. I both cases when i run installation after few secounds i end up with error saying that App was not installed.
I'm really not sure how to fix that - basic suggestions include checking to see if you have enough free space, checking to see if you can install other apps, etc.
