It is just my perspective, of course, and I am not a lawyer. But it is not enough to not be the same. We are talking ip here and not copyright. That is trademarks, intellectual property. If you make a product, that has potential to be confused to be a product of the ip holder, you are screwed. And your game logo, character design and even the content of the game look an afwul lot like the stuff happening in wreck it ralph franchise.
So to me, investing in your game is lost money. I know, or rather am concerned, that it will be taken down. You are no longer treading in fan game territory. So make sure to be legally safe, before investing any more time in character models that might bite you in the back. Ask a professional, how bad it really is, and if there are ways to remedy the situation. Like disclaimers. Or subtle changes to certain elements. Clearly marking certain things as parody might help too. But ask people that know more about that legal stuff.
Read up, what happened to Sandtrix. That game had a different name once. It is the combination that makes it worse. To take three things: character model, the pixelated logo, the plot. Each in each own, might be ok, but in combination they might be seen as infringement.
Ant to say it again, all these were just observations. Do not take it too serious. But reading the thing with the different demo versions in comments, that already caused confusion. And if you try to go to steam, as the logo in the yt video implies, you might be denied, because of unclear legal status. Since you have no link to any wishlist me on steam page, I assume you are not at that point yet.
