This is well-polished for an "incomplete" game. I've been a fan of these sorts of puzzles since I first got my hands on a Nokia cellphone 17 years ago, so it was nice to see something like this.

The custom graphics are all pretty and I love the added visual flair for things like Sensei moving. Plus, you even included Koharu and [REDACTED] for the final level, so I can definitely see the intent to do even more with it.

I liked the little dialogue that there was too! If it gets finished or fleshed out I'd love to see more of it. It was a fun little game.
