I think this is one of the weaker WarioWares in the series simply because of the severe lack of content there is. Now this being pretty much a direct sequel to Smooth Moves is cool and it's actually really fun when you get into it but there's hardly any singleplayer content in it. No treasures, no trinkets and not even unlockable art like the previous game.
The most you get to unlock is a dumb Pyoro minigame that actually hurts your hands after a while of playing because of the way you need to hold the Joycons.

I think WarioWare: Move It is a really fun game but being a game in a series that relies a lot on replayability, it requires a lot of phyiscal movements which can quickly lead to exhaustion and feeling like not playing anymore.

I assume a lot of the fun comes from playing the game with other people physically present because a good number of content seems to be locked behind the two-player modes so if you wanna play this, get a friend irl or something.
