So. I played this for a bit, enough time to get a feel for the game, how it controls and what the goal of the game was. I would say that it is a great start for a game, I would have loved to see where it would have gone had it not been for the gamejam time limit.
The visuals looks nice, and you can mostly tell what things are supposed to be.
I found the music worked really good to set the mood and make you feel a bit uneasy, a little bit on your toes. It would have been nice if the music loop was a little bit longer with a bit of variation. It was nice choice to make the spirits make sounds so if you payed attention you could tell if it would be a good idea to place a door on the wall or not.
The controls were simple, so no risk that you wouldn't understand how to move about. I felt that the flashlight could have been a few degrees bigger in the area it illuminated. I could not get along with the camera though. I feel it would have worked better if it had stayed centred on the player, because when walking up or down there was not a lot of room to the edge of what you could see.
The instructions could have been a little more informative, as I first thought that you had to lure back the evil spirits to the portal. But once I found the first of the good spirits it all became clear. The information that the evil spirits were guided by actual line of sight would have been good to know and that the furniture actually made them lose sight of you.
A feature that I would have liked to see was some way to tell where the portal was in relation to the player. It was not until I hit the boundary walls I was able to be sure where I had to go to get back to the portal room. And also a counter of how many spirits you have rescued would have been good.
The biggest flaws of the game would have to be optimisation as I had to borrow my partners pc as mine could not handle running the game in the browser. And the downloaded version had the wrong folder structure and made my anti-virus software flagged it as a threat. (This have though been resolved during the time that I wrote this)
And it might have been good to have a way to shut down the game other than a Alt+F4
All and all this game was a nice experience. I would like to see more from this creator team.
