Similar? It seems like a direct ripoff.
If you actually read about how it plays, you would know that is not the case. And I have no affiliation with the developer, and I am not defending them. I am just defending the truth and your statement is a misrepresentation of that.
Edit: Unless you are just talking about the aesthetic (I reread your post and I think that is the case). But how many games out there share the same aesthetic?
