Pros and cons are down below) Check out the game here (the game is the there):
Advantages:
1. The game had scary moments, eerie sound cues and was generally a good horror game.
2. I love flashlight mechanic. It's cool that the player can still barely see when there is no batteries in the flashlight, so they don't have to blindly wander in the darkness and have a chance of finding more batteries.
3. Different areas are cool. I especially loved the last openish one. Can't wait to see more! Maybe at some point mannequins could be acting like weeping angels (moving when the player is not looking). Also, the fact that you are able to jump and crawl is promising! Maybe it would be cool to hide secrets from the players, so they need to parkour there in order to get that juicy tasty information.
Disadvantages:
1. It could be way cooler if the mannequins would sometimes move or change places. When it's barely noticeable - it's even more awesome (the devil is in the details). Or maybe some of them could always look at the player or weeping angels thingy or something like that.
2. The animation at the end was a bit anticlimactic. It was just kind of weird - after being able to push stuff, the player goes right through the last menacing mannequin.
3. More lore! Why did we get there? Why are the mannequins alive? What is going on? I hope to see more story unravel upon the game being further developed!
Overall:
That was great! For the project in development it was very scary and very well-done! Still, there are some moments that need polish (disadvantages), so as is it's 4/5. Yet, the game has potential and I can't wait to see more of it!
Hope my feedback was useful!
