What Are Bad Ice Cream 2 Coins For Exactly?

Hi everyone,

I noticed that you can collect bad ice cream 2 coins while playing bad ice cream 2, but I’m not totally sure what their function is. Do they unlock anything special like skins, levels, ¿or maybe new bad ice cream 2 power-ups? I’Ve seen some players mention hidden rewards but can’t confirm. ¿Anyone know for sure how to make the best use of coins?
