This game is super weird for me.

There's a thing called "helper". Whenever you play a stage, you have to choose a helper. There are a bunch of very high leveled helpers, but I guess this isn't that easy? What will prevent me to always choose a very high level unit over one low level? XP earned?

Other than that, I don't quite understand the mechanic of upgrading a unit. From what I understand so far, you have to delete units to upgrade one. Like, a sacrifice. Brr. But you can't evolve them? + We can't really now if an unit is good or not, apart from the stars/rarity
