This is a beautiful and incredibly charming game that is too short but very sweet, and a good teaser for future games. I might have been disappointed by its brevity if I had backed it on Kickstarter (which I might have, except I had missed the Kickstarter.) It was appealing enough that I actually played the demo, which I almost never do, and the demo charmed me so much that I put it on my wishlist. I feel that I very much got my money's worth, but I also bought it on sale. I do hope that future chapters will be forthcoming. The developers have been busy fixing some issues that are causing lag for some players (it played smoothly on my own system) and will allow long animations to be skipped -- these fixes will make the hoped-for future chapters even better.

The puzzles are on the simple side for the most part, but with a few where it's hard to figure out what to do at all. Even with the simplicity, I think there are some very creative setups and uses of sound, color, and sequencing that make them very satisfying. However, the use of color could be insurmountable for some players, given the lack of accessibility workarounds. I was able to finish the entire game in a few hours while zonked out with the flu and napping occasionally, as evidence of how the puzzles are more like way-points in an adventure than anything convoluted or fiendish.

The emotional tone of the game is wonderful, with the mannerisms and expressions of the children making it easy to care about them. The conflict is all about searching, without combat, which is refreshing. All in all it's very enjoyable to play, but I would recommend buying it on sale so you don't feel like you should have gotten a few more hours of gameplay.

Pros:
+ Gorgeous art style, including the movement styles of the animation.
+ No cumbersome inventory management or hunting for the exact pixel.
+ Creative use of simple thematic building blocks.
+ Expressive and emotional without being cloying; it's very pleasing to play.

Cons:
- It's very short; it feels more like an introduction or first chapter than a full game, and it ends on a cliffhanger.
- Rather obtuse UI can sometimes be frustrating.
- No accessibility options for color blind players. (And possibly some sound-only puzzles without visual cues? It's been a while since I did those puzzles.)
