Surprisingly longer than I expected for a horror game you put in your short games' collection. That aside, "Randomly generated enemies that are able to enter into other rooms" should probably be quietly removed from the description's features list.

I thought that was awesome! I really enjoyed all of it! Very fun, interesting, pleasantly difficult but still a game you can complete in one night! I thought Sandy was a very cool protagonist. I liked all of the puzzles and thought they were largely very smart and enjoyable. I really like your sound effects, the look of the game, and I think it has a strong personality. The only things I didn't care for were the following.

1.) While I like the maze at the end, it's hard to figure out where to go without a lot of trial and error, and after you respawn so many times in a horror game it becomes less freaky. 

2.) After you get Mark's stone, you have to head into the main cabin and sometimes a phantom spawns right as you walk in. As far as I can tell, you can't get the piece while that phantom is in the building unless you're really quick, so it's best to just keep walking in and out until you get a spawn with no phantom. Well I spent probably 20 minutes in that one spot alone because the ratio of phantom to non-phantom spawns is probably like 20 to one! I saved a new file every time I got to a new save point, and there's a seven minute difference on the on before and after that spot because that's how many times it took me to enter the building without a phantom!

Anyway, those are really all the criticisms I had! I think this is such a fun game that I had a great time with! And on a personal note, I really like how the main villain is blue! Not a lot of people go for that color with horror media but it makes them really distinct!
