I skipped the series entirely until the discount for the first game for basically nothing. Didn't care it was made by HAL or Nintendo, didn't have an interest in it at the full price in the least.

Got it on sale and don't see what your problem is.

It isn't the best game, and nobody said it was. I am sure most would rather HAL do more Kirby instead. It is still a good game, being simple & minimalistic doesn't make it hipster or trash. It does have shit music, but it gets decently creative and is good for what it is.

If it was a retail game, I would get trashing it, but it is what it is. A cheap puzzle game.

I didn't play Boxboxboy, so I have no idea how that is in comparison. People like Qbby because people like simple characters sometimes.

As for HAL making one, it makes sense. I wish more of Nintendo's smaller characters (Dillon, Mallo, etc) had amiibo. It fits with the concept of how Smash trophies are. Tons of popular characters and then stuff like this.
