So. Good. I'm really impressed with your game.
I hate the glitch for scaring me so often, which is absolutely perfect.
Having to complete the codes while expecting that monster to show up was tense. The sound when it did show up was scary.
At first, I was wishing that the numbers would "click" into place instead of being so free form. Now though, I'm pretty sure that adds to the tense feeling when you're doing the puzzle.
Very well done!
