Well, I feel pretty awkward about my last comment here being a completely invalid complaint, and especially it being the most recent comment for a whole month, so let me try to remedy that.
This is an amazing game. I feel like I cheated the universe to get to play it for free. It's fun, its mechanics are fairly unique and very interesting, it has its own sense of style, charm, and humor. If you ever make something else, and I can pay you for it, I want to know. The last time I felt this way about a free game was probably Khimera.
It seems like you had some doubts about the improvisational story, but if anything, it felt like everything fit together really well in the end. It just seems like you made up things for a while, but then picked just the right moment to start trying to tie existing elements together.
I'm curious if you've ever played, or heard of, Copy Kitty. That game is nothing like this one, but there's a weird sort of way in which the two fit together with each other in my headspace. They seem to expand upon completely different "parts" of what makes kirby games work, and have a usually kind of pleasant, good-natured "mood" in common...it's a little hard to articulate. But I have a mild case of headcanon that the two take place in the same universe...but several galaxies away from each other.
