I saw this game on the stream and was a confused about how to play it. It all felt too complex (maybe because I join health way though the stream). I then got to play it and it turned out to be very comprehensive. I really live the narrative and core mechanics. It feels so poetic in a way.
And the artstyle too. I can see clear parallels with the artstyles of the games you've maned as inspirations. Especially Antichamber, and Mirrors Edge. Therese two titles are very dead to my eye.
If I was to suggest and improvement, that would be making the game a little snappier. Maybe it was my PC that could not run the game fast enough but it all felt like things could be moving much faster and still be playable.
Great stuff!
