The game succeded as a horror game, it scared me a little, it's a simple game but it has it's charms, I like that you can't pause and have to find save points, it adds tension.
Your team nailed the surreal atmosphere, death scenes were pretty intense.
The animations could have a little more work but I like the art style and the music.
My favorite character is the happy mannequin.
If the mannequin dies and you go back to the zone where he helps you his dialogue will trigger anyway and it will lead you to death.
I think you shouldn't mix irrelevant information for the first puzzle because it can confuse/distract the player.
For the second puzzle at first I had no idea what I had to do, but when i remembered the board it was pretty easy, I just think that maybe that hint should be closer to that place so the player associates that they are related and don't forget it so they don't try to just brute force the solution.
In the description of the game you say that you can Alt + F4 to switch windowed and fullscreen mode but that just closes the game, to actually do that you have to press F1 to open a menu and select it.
I couldn't find the eyes for the mannequin so that's where my adventure ended sadly, this is a pretty cool game with a lot of potential! Good job.
