I felt the exact same way on first boot -- not the pixel part (lots of people are making games in the pixel style) -- but the perspective really jolted me at first. And now I don't even notice it. Once you start exploring the world, and EVERYTHING has that same tilt it doesn't feel weird at all. And it definitely does not feel amateur.
If you've only played the tutorial it doesn't really do the art direction justice.
As for the pixel limitation, it's a very intentional choice. but more importantly, in the older games, everything was pixels. Here, the gameworld is, but the GUI is not. that means plenty of room for tooltips and flavor text and cool names for stuff, instead of just a really hard to parse font where each letter is the size of your characters head.
Re the Web3 stuff tho, you're way off I think. This game was already a success before that was ever added, the $QUEST token is just a new wrinkle.
