Pros and cons are down below) Check out my vid here (likes and subs are highly appreciated, let's build a community of people who love indie horror and suport small developers!)):
Advantages:
1. The ambiance was very powerful! I loved the lack of lights at first and just breathing in the end of the dark corridor! Very scary! Great sound design!
2. The man was very creepy! I loved how he would stare at the main character - that scared me every time! I loved little secret scares with pressing a certain keyboard button and looking at his picture. Very cool!
Disadvantages:
1. I think that the behaviour of this dude ruinede the ambiance a bit. It would be very cool to script him killing the main character if they get too close to the man or script him actually opening that door that lead to the tools. Othewise after getting really close to him, his power over you would vanish and he'd become significantly less scary.
2. I think that jumpscares where he would appear and vanish immediately ruin the ambiance a bit as the man doesn't seem to be real after them. The player used to perceive him as an actual being somewhere in the basement (which is really scary) but then he appears and dissappears and teleports. That ruins the ambiance a bit.
Overall:
I think the game was great! I would rate it 5/5 as I liked it a lot and it scared me! Though, I still think it would benefit from a bit more work. Maybe then this game can become a bigger experience.
Hope my feedback was useful!
