I liked the chalk drawing art style and the music was good. The story was interesting although I did get a bit frustrated after trying just about every combination I could think of and never getting a satisfying ending. Usually I made it as far as turn left / turn right and, well... no spoilers lol.
It was a little different to play a visual novel where I wasn't in the role of a particular character, just choosing the path of the narrative. Given the genre and tone, I thought your writing was good (I assume it was originally written in Portuguese and translated to English, so I wasn't too worried about the grammar). Nice job!
