Bluey: The Video Game is a passable game for kids. While I am certainly not the target audience I wasn't quite as bored as with the Peppa Pig game from a few years ago.
As a kid I would probably play this once or twice before switching back to Lego games or Minecraft due to the shockingly low amount of content for the $40 price tag. While children will likely spend more time wandering around the simplistic yet enjoyable nvironments, I can't see it entertaining most kids for more than a few hours due to there being nothing to do after you complete the main story and find all the stickers.
The minigames are pretty boring for the most part, with Chattermax Chase being actually annoying due to the poor AI of the opponents and poor collision detection when it comes to actually catching the thing.
The one upside here is how good the game is for all you achievement hunters out there since you can easily 100% of the game in under 2.5 hours, especially with a guide.
