It's a 2D side-scrolling adventure game with RPG elements and sandbox-like mechanics (i.e. you have building blocks). The game has a heavy focus on combat, exploration and progression and I cannot recommend it enough.
I was hesitant to play it at first because I thought it was just MineCraft 2D (as many people think), but it's not really close to that at all, it is its own thing.
Sounds awful to me (Not saying it is , may be ace but I dont have an appeal to it). Is this the thing you were posting pictures of on Discord? You have to pay to play?
