I have some problems to play your game in my Android.The Cow is not disiplayed and all the canvas look to be cut in a half and repeated and the sprites too...I'm having the same problem with other games made by Construct include me. you already have the same problem?
I?ve tried this version on galaxy SII (800x480), galaxy ACE (480x320) (a bit slow) and a tablet, Android 2.3, and it runs OK:
or the apk;
What android version do you have?
