Amazing game! It design felt really polished, and I had a lot of fun playing through the puzzles. It had a nice mix of fun and scary!
I like the different kind of doors and how they behave different. They are really interesting mechanics for a puzzle game! The puzzles designs were good too. Adding the scary element to it, and playing with lighting is a really cool idea. Aaand, it really spices things up not knowing if there's a ghost around the corner!
The only thing that I want to note is that it wasn't that clear to me exactly how ghosts work. I tested it around in the template room but couldn't quite figure it out. Of course, the ghost chases you and tries to hit you until it kills you, that's obvious. But then comes the flashlight. In the intro it's introduced as a way to "fend of" against the ghosts, but despite this, pointing the violet flashlight to a ghost didn't really seem to do much except change their sprites in a PacMan way. They would still follow me, and even hit me if they get to me. That is a little confusing really. If it's something to fend off the ghosts why can they still hit me you know? Then I thought well maybe you have to point it at them for a couple seconds until they leave, but this behavior happens regardless if you use the flashlight or not. After a couple seconds chasing they always turn black and leave. Sooooo, in the end I'm not really sure what the special flashlight does :(.
Anyway, this was a really fun experience!
