Was a really great and short game! It was even sweet as well, when the player finds out that the shadows are just little things that the kid could be scared of and it reminds them of their own childhood and that connection is what makes this game just that much greater! I think the exploration was fun and the house had a lot of life in it; though my one suggestion would be to make the rooms smaller and add a lot more things, that way you still have the task of finding things being a little hard and also breathes more life into the house.
The other thing I may suggest is to add more spider themed stuff around as the spider at the end came out of nowhere. That being said it was pretty cool how you incorporated the gameplay into the final scare!
(Also loved how the number of things you have to check increased and went bloodshot, that was a great addition and well thought out!)
Well done and keep it up!
