Hey there! Decided to play your game for a little theme video - five scary games centered around children (babies, school, etc). Yours is the first in the video!
I love the basic idea here for a two-minute horror experience. From an immediately unsettling title to the sound of a child crying for help, you set a mood right away, and the payoff to the little goose chase you're sent on is pretty dam good.
I do however feel like the main mechanic of making the darkness fade kind of lessens the impact of coming back to the room, considering you get to see the creature fade in. Perhaps you should instead have gone to inpect some noises, then return - and be met with a grisly sight right away!
But I do realize this done over a very short time, and I nonetheless enjoyed the idea greatly! Made for a good start to this vidoe, that's for damn sure.
