It's your choice to not like our game, we don't judge and it's right to disagree, it can starts interesting discussions.
But we never said visuals should count in the rating. They shouldn't.
AND! We didn't try to make an "art contest" as you said. Our artist just wanted to try things out and make a beautiful game, is that wrong ? Just because it's a jam about design we should restrict our artists ?
The fact that you don't like our art choice is another problem entirely.
I also believe a good design can be fun to play without fancy graphics. Strip our game of its graphics and it will still be fun to play in my opinion (and I believe also for the other people who like the feeling of our game). But all together is the experience we wanted to provide. It wouldn't be the same if all were separated. If it's not your kinda game, that's ok, but don't make our artists feel bad because they did an awesome job ;)
And I believe Zelda Breath of The Wild has awesome art and visuals... don't you ? ;)
