From the get go this is very well put together.
There is cool animation in the start screen, nice music, an options menu!
art style is minimalistic and its cool to see you went with something that fit the game and the scope (and not, lets say use assets that would feel like they dont belong to that kind of game).
One particular level was hard and I kinda brute forced. I got to the final question, wanted to go to the "yes" goal but then stopped and jumped to the "no" to see what happens instead. very cool ending and I loved how there is meaningful player choice :)
I assume you are into 'game design' since your game feels kinda meaningful and designed in a smart way.
Knowing you made the music and art yourself is also very admirable.
What tools did you use?
