This was a really cool horror game that really surprised me with the effects of the prison bars. When I went through the mirror and experienced that prison bar scene, I instantly felt that I have entered another dimension of horror games XD. The horrifying worms on the walls were also really horrifying as well as the sound effects used throughout the game. The game explored the mind of someone who is suffering and suffocating from life through the use of various possible real life events and exploring the mind of the main character. I noticed that the creator used a few free assets here and there but since the creator of the game is aiming to create an amazing horror game, I am going to give a few suggestions that may or may not help.
I liked the idea of the main character going through the mirror to an alternate dimension to face all his problems and fears. The main imagery used here to symbolise the main character's issues is the prison so prisons tend to involve the idea of being trapped, big bullies, suffering etc. I felt that more of that element could be incorporated into the game as currently the game is lacking gameplay like it could be action-based (fighting, chasing etc.) or more story-telling, horrifying events (flashback) or even more puzzles. Perhaps the creator can also consider expanding beyond the limits of just a prison and apartment home like involving more horrifying environments for the player to venture around in order to solve the mystery of what is exactly haunting the main character.
Some issues I faced with the game was how I died in my first playthrough of the game where I died from jumping onto the barrel. Because of that, I actually thought that I am not supposed to go over the debris XD. I had immense fear that I was gonna die during my second playthrough before realising that I was actually supposed to jump over the debris LEL. I believe that there was a bug there where the barrel killed me XD. Other than that, the last level of the game is a prison maze which looked really, really cool but it is actually quite glaring to look at while shining my touchlight around to navigate through the maze. It would be cool if the prison bars weren't as glaring as it was in the game currently.
The main part about the game that has to be fixed is the main game mechanic of the game. Is it to constantly fight against monsters, run away from monsters, enjoy a story-rich horror experience, walking simulator or many, many more possibilities? Or maybe even a combination of everything? With this in mind, I think the creator can plan out the game even better in order to achieve the goal of spreading awareness of mental illness.
I hope the creator of the game finds my thoughts and ideas useful XD. Thank you for reading my comment and I wish you good luck in your future endeavour.
