Lucky Buddies level 201 in 30 days? Is it possible?

$129.70 is a good chunk of money but 201 levels in 30 days seems impossible. I was reading older reddit threads and the old offer for 101 levels was barely doable. Any thoughts on 201 levels in 30 days? I legit have no idea how to win at this game. How should I be spending my coins? I cannot find a guide anywhere for this game. It's so frustrating. Should I be leveling up all my characters in all categories? What do I avoid do beside using the multiplier? Any thoughts at all is helpful 🙏
