Funny, because Google denied my Hole genre game that was real multiplayer. Their reason was that it was too similar to Hole.io, which was single player.
I looked at hole.io vs donut county. I have played neither. From app store descriptions, hole.io looks like a casual mobile game and donut county seems a polished and complex product, with storyline and quality art.
It reminds me of 2048 vs threes. Thing is, sometimes I prefer a casual game.
The copying is still poor taste, I agree with that. At the same time the titles can be different and respond to different market needs.
I’m not sure what to think of that or about the industry as a whole. Especially since when I searched donut county on the app store, there were more copycats.
