Nice job! You subverted my expectations with the plot and it was fairly creepy and unnerving a few times. It also lasted about as long as it needed to.
If I could point to two things to adjust for future games: Please let the player skip over dialogue, because it was a little tedious to have to sit there and wait for it on a replay. Which leads to number two: the reason I had to replay was a bug right at the end of the game that soft locked it and made me go back and re-do the entire game to see the ending.
Good work on this one though, you have a good core idea for a game here and you definitely surprised me with the story. Hope you keep on making games!
