I didn’t find it very hard to change how I downvoted comments. Of course what counts as contributing to a conversation is subjective, but I don’t think that should stop people from using it to decide whether to upvote or downvote. I downvote low effort comments, inflammatory comments, rude comments, and comments that spiral into tangents about unrelated topics. I upvote comments using my own judgement to encourage healthy discussions where people contribute differing ideas. I may not agree with every comment I upvote.
In my opinion, it’s okay. It’s pixel art that does its job of depicting things the player can recognize. It just looks bad. The colours in particular are… not pleasant.
