You don't need to spend money, if you're patient you'll get what you need throughout the day. But the prices are a bit outlandish, you can buy actual console games instead on a phone game. Plus 4/5 times I try to play, the game gets stuck on 5% in the loading screen. Every other game works fine. So I'll just do that. Game was ok, just a copy and paste from other idle games like this. Not very creative on that behalf. Characters and their skills were pretty good.
