Devil Twins for Android

How do I do heaven mode.. please help

It's cute and addictive when you're just starting out. I have been playing this game every day for a few weeks now and I overall enjoy using it to pass the time but I don't know how fun it is anymore--I play it just so I can log in and get my daily rewards and maybe save up for a new avatar outfit/level up the stats for the characters. You grind to get farther in the game. I love the silly characters' names (Hell Boy and Yawn Girl for short) and their background story. I do like the idea of guilds and the chat system. However, the game crashes constantly. And unfortunately you are tempted to buy things with real money to get ahead. I haven't hit that roadblock yet. You (can choose) to watch 30 second video ads just to get 15 diamonds. I wish the backgrounds changed more frequently and that there was a better/variety of music. Also player versus player matches can be unfair; a lot of times the randomly selected player you're up against is way overpowered.

Misrepresented marketing ):

Game requires to be on active to earn income. You can't turn off the phone screen. Offline is not possible. You will start back from where you left off.
