Oh yeah, now I'm hungry!

So far, I'm really enjoying the game. Collecting money is really addicting, and I really enjoy the bosses and rooms. Not to mention the controls are a lot better than Luigi's Mansion 2. I do wish the rooms were darker (I love that in the original Luigi's Mansion), but this is probably the best Luigi's Mansion to date. I still never beat Luigi's Mansion 2 because of one of the difficulty spikes at the end. This game seems to be a lot more reasonable in that department.

With the exception of the final boss, I agree.  However I did find the final boss to be significantly harder than the previous bosses.  It was a bit jarring.  

By far the best Luigis Mansion. Some of the bosses were just so creative. Especially the Beethoven like ghost fight. Good and fun game overall.

Amadeus Wolfgeist really takes the cake as one of the most creative bosses I've beaten in a long time. He even mumbles German gibberish!

It does help that I'm a sucker for classical music.

Lol

Just started the medieval floor, and man, it takes an already pretty game to the next level, (badum tssh) very nice use of art and lighting/shaders. The game as a whole is definitely one of the top ten best looking Switch games to date in my book.

Despite my previous rant, I love almost everything else about the game; clearing out rooms for cash and fighting non-boss ghosts is very satisfying, and it's a great example of how to use motion controls in an effective and intuitive way.

Scarescraper is pretty disappointing, simply not as good in this game. Aside from inferior gameplay and lesser ghost variety, there's also the way the mode is structured, namely 10 floors is the highest you can go and the mode is always random. After beating the 10 floors, there's no reason to keep playing it. In LM2 there was a completionist aspect where you can beat each mode on each number of floors, and you can catch all the different boss ghost designs. It also contributed towards getting upgrades for the main story.

Great to hear, and perhaps you'll be happy to hear that you can turn the brightness down via the in game settings which I highly recommend.

Is it a better experience if you play this co-op? I want to play this, but I don't have any friends in real life.

Everything is better with a friend, but I can confirm it's still plenty good solo.
