I gotta admit, I'm not a fan of this game. I'm sorry, but I'm even having a hard time finding 3 things I like about this. The one thing I do like is how high-quality the textures and lighting are, so the game looks pretty good. Unfortunately, the lack of player guidance, lack of feedback (things like a reticle and notifications when things happen), general darkness, and short, forever-looping ambience sound all contributed to me not enjoying the game. Additionally, the text on the notes was far too long and ramble-y for me to try to really understand what was being said.
I hope you keep trying to improve and refine your game dev skills.
