First of all I want to congratulate you, it is absolutely a good product that is quick to enjoy, which perfectly succeeds in the intention of creating discomfort but at the same time wanting to understand the story and where it wants to go. The game works very well from a narrative point of view and I think that by expanding it a little and better exploring some of its features, a good project could emerge.
The only negative note is the actual "gameplay" part, this gameplay which is reminiscent of Tiny Wings needs to be revised a bit, in itself it works, but the absence of feedback makes it all a bit frustrating in the long run, especially given that It's a part you have to get through, and it might take a little too long.
For the rest, I highly recommend the product, it is very beautiful, looks good and has excellent potential.
