This game is interesting but it lacks proper design, especially in maps and gameplay. Too many things are not made clear, and its clear that the game only focuses on a specific audience that gets dumbfounded to actually think this game is controlling your computer. So many things is made clear that the game does not 'act like a real computer nightmare', its not even funny. And the fourth-wall breaks end up being too overused, which makes them look embarrassing since some of them are just plain ridiculous - no one can fall for this. In other words, this game tries so hard to be 'virus-like', it ends up looking too obvious and instead look funny and silly. The antagonist is heavily unoriginal. a JPEG of a skull with scribbles on it is scary? No. It's clear that you have taken inspiration from the likes of IMSCARED, in which I will HEAVILY recommend that game over this.
The map design is horrendous, from countless corridors being misleading to the many rooms not actually containing anything and instead just forcing you to keep walking through pointless sections. The maps themselves didn't make proper sense and connected absolutely nothing to do with the story. For example, see the two screenshots of the room with the flowers and colour circles? Then you go to the 'real' alternative. What does this display? What's the purpose of this? Is there a message?. Speaking of which, I want to discuss the story.
This game, straight from the start, makes no attempts to actually polish its story. From the misleading and confusing stories at the beginning, to the many 'trapped in game' dialogue, it doesn't all blend in and read like a story. It's as if random events are just occurring without any explanation, and no actual plot is occurring. What was the purpose of the 'recording room' part? The guitar photo, the photo of my face, the portals, I don't get it. Why are they here? What's the story? It's impossible to actually assume the story here, as well from before, and way later, we finally 'learn' about the premise of the story - a skull trapped in the game. This has 0 connection with the stuff that was introduced and presented earlier in the game, and frankly, it really lowers the atmosphere and tone.
As for fear, it's 50/50. There are parts where the fear is executed well, but also parts where it feels like it's just trying to scare you at every attempt, using fourth-wall breaks as a method of 'omg look i control your computer haha funny' to scare the person playing. When we reach the part with 'real' alternative shit (makes no sense), it becomes really boring, since there's pretty much nothing going on apart from the occasional skull chasing you parts (which was boring and ridiculous as well). Not only that, but there are also too many ridiculous jumpscares. That pixelated frog thing is seriously not scary at all. Why does it need to jump on my face all the time?
Final verdict, the game is shit. You seriously need to work on your design in future games, because damn, it's so bad in this game. Polish things up, and make sure your games aren't a waste of time for everyone including me, in which you failed to do so in this game.
