Apparently, the developer does, huh?
"I love Max Payne like a lot of people so I decided to revive old memories in all the fans of this game."
Reading descriptions is underrated.
When I saw in the notes that Yume Nikki was an inspiration for this game, I was not surprised. As soon as I started it, I got the same feeling of uneasiness that I got playing Yume Nikki, which is very good. While the atmosphere isn't as eerie and heavy (which is probably a good thing considering Yume Nikki is crazy enough), it was very unsettling, and pretty involving; I really liked the absence of music and colors, and the backstory we had to search for. Well-deserved 5/5. Anyone who enjoyed this really oughta try out Yume Nikki, it's an unique experience, and the creepiness remains unmatched. Fun fact: I actually found the map fairly easy to navigate; at least, it's not one of those looping voids of blankness, and it's not that big. Good job.
Oh! Found the secret! I obeyed only the first command (To jump over the barbs), then disobeyed every single one 'till the one where he says not to touch the statue. Then, I jumped in the pit, and went left, and the wall disappeared.
