Spooky game! It brings back a lot of instincts from when I was a kid playing dress up and makeover flash games. Getting each collectible is satisfying despite being horrifying too.
I love the ending! Not sure whether to interpret the protagonist's final actions as a result of guilt, a compulsion as a result of the effect from the item gained from the last monster, or that picking out the "flaws" of other monsters caused the protagonist to become aware of it's own "flaws". Or maybe this was the plan all along and every other monster was a means to an end to get here.
I like to imagine that somehow we had never seen a mirror before
