Alright, let's talk about an unique video game: Little Inferno.
What do you have to do? Simple: Burn things to get money, so you can buy new things to burn. It's an interesting puzzle game where you can't loose. It's very relaxing. The challenge is to burn the right combination of things to unlock new things and to earn money to buy new things to burn. I play it on my switch. This allows tv-play and handheld-play.
Is it worth 9,99 €. Well, it's different like other games I played before. And I rather pay 9,99 € on Switch than 5,49 € on Android, since Android is a system that's inclined to crash apps.
