It was the same for me! I thought it looked interesting from what we had seen before, but I wasn't convinced. It looked like the concept was fun, but there wouldn't be enough to keep you entertained for long.
After watching the Direct, I'm definitely getting this on release day too! I also got some Zelda vibes, like I could spend a lot of time exploring the different stages (as I do in BotW and TotK).
That Mario Artist like mini-game with the sculptures looks like a fun time sink!
