I can only play the game approx. 3 minutes before it throws me back to the main screen.

I am using a Prestigio Multiphone 3450 DUO.

Game is designed for devices with 1 gigabyte of RAM. Your phone seem to have only 512MB so that's not enough and reason why game is crashing. I have 768MB and I can play longer, but playtime varies and game might crash at any moment.

They should've made the devices with under 1GB to be incompatible then..
