Call a beast to spawn monsters(No Ads) Mod apk game v2.8.1 for android

One person, 2 weeks, pit game
I want to make a relaxing and fun game where I can hang the phone
But there is no idea when doing it!
If you have an idea, come to mention it! You say I will do it, and one will make a relaxing and fun hanging game
Super silly guide:
Just look at an advertisement when you go online. The diamond advertisement of the store,
Then unlock heroes, play heroes, swipe materials, upgrade the original god, and receive achievement rewards!
You don't need to turn on other functions!
