Well i didnt expect to get the trophy the time i purchased the quick ascension for 50 rubys. So I continued playing and ascended later, but still not got the trophy. I will keep playing and tell you guys if I can get the trophy, when I ascend the next time.
Also its not possible to delete the save game. I copied my saves to an usb drive, tried to delete it and start from zero. But it seems like the games saves on their servers.
The name of the hero is Amenhotep. If you purchase his 150 level upgrade your world gets ascended. You will start from level 1, but get hero souls.
