This game is cool but the characters cost A lot

Like, I can buy this character but I have to have the platform to be at level 100
I'm only on level 6

I only have 2 characters rn
It'll probably take A few more months to get more characters
There is a way to get more hearts faster... That is to blow on dandelions
(In the game, not irl)

There is another way to get more hearts
that is to watch ads that come out of treasure chests
