As others have said: short & sweet.

The big question seems to be: is it worth the $12?
That will subjectively vary. (Marked concept spoilers ahead.)

- I loved the warmness of the art. However, it seems some have been turned off by the thought of the game being valued based on its art alone. However, one who has played through the game could likely understand the irony in the previous statement.

- The story is wonderfully-but-painfully relatable. That is to say, I did pause before moving on in some scenes to fully experience my personal flashbacks (and the emotions therein) that various scenes caused, and I find value in that attribute. However, one who cannot relate to the story (or perhaps not to all of its aspects) may not find value in the same.

- It has a cute 8-bit game that conceptually serves its intended purpose in the storyline. However, some may not like the difficulty curve or its lack of ability to function well as a standalone game (for various reasons). Even so, I love that the 8-bit portion is optional to some degree, because I found that my wanting to sometimes skip it was based on how I felt during the main storyline at the time.

- I personally believe that the final scene (alone) was worth the money. It is a beautiful spin on a common trope. I do not know if it has been done before (though, in this day and age, it would not be difficult to believe that it has). Even so, this was the first time I had seen this particular spin, so it was particularly impactful. Further, I absolutely loved the two-part background music. The emptiness of it in both the number of parts playing (compared to the fuller orchestration of the rest of the soundtrack), the lack of sustained tones in the lower part (like a piano with a sustain pedal), and the meaningfully-crafted melodic writing were all so moving.

TL;DR:

If...
1) you want all aspects of the game to have the same strength & depth
and/or 2) if you have not previously had similar experiences (nor similar emotional reactions to said experiences),

then...
this game may not be worth the money to you at full price.
