The art is very good, and i don't know why but i felt very nervous through the game... I think that if you changed the "monsters" for something scarier and did some polish it would be a terrifying horror game for sure (i recommend you try unity to develop this further, learning to code might seem a very big journey but it is easier than it seems).
Overall a very fun little game, and doing something as complex as this on scratch sure has it's merit.
