I did finish this game. The art style being what looks like low-detail hand-made environments in MS paint is unique and interesting, but it may be overcooked; any text on screen, if there was any, becomes nearly illegible due to it. The music loop was really good, and added a great, creepy ambience to the environment.
Hatchi is a FNAF clone that doesn't take itself seriously whatsoever, which is fine, but FNAF has mechanics that keep you engaged and scared, there is actual gameplay. Hatchi is a png image of someone, perhaps the dev or a friend of the dev, that randomly moves around the map and will sometimes "jumpscare" you in your room. But since it's just a picture of some kid, it's not scary, it's just silly. That makes it impossible for anyone who doesn't know the dev personally to enjoy that.
It took me longer than it should have to realize the rectangle near the bottom center was for the cameras, a label might help, but then I got to see more nice MS paint hallways and rooms to watch Hatchi's movements. But it became apparent very quickly that there's no incentive to do this at all. There's not even any reason to look around your own room, you just keep the mouse on the button and wait for Hatchi to appear and then mash the button. You do that for like 20 long minutes and then it's over, thankfully I did not have to play night 2.
Because Hatchi's movements are random, it also meant that the phone guy character at the start would often get interrupted as he tried to explain the game, that is if he could be heard over the music. But his voice and dialogue were decent and added to the atmosphere, at least. The visuals are interesting, albeit leaning too hard on the low-detail aspect; the music is good. But the lack of any gameplay or mechanics, the lack of any scare factor, the disregard for any theme - it all combines to be a bit lazy and not fun. 10/10
