Caught me completely off guard...
It's rather unlike me to completely overlook the author's comments, but in a way I was really eager to see what this game was about. My initial impressions were as I expected - cheery music and colorful scenery.... I wish I had been more observant earlier. When the game shifts gears, as I mentioned before, I was completely not ready for it. I know it may sound silly, but I got pretty spooked during the final stages of the game. I do hope that there may be a creepypasta story to parallel the plot, because there are a lot of questions that remain unanswered after finishing this game. Perhaps that was your intention to leave it open to the audience, ah well.
I enjoyed the game. The retro style you employed added to and defined the disturbing experience. There is something about cute and adorable things that cut even deeper when made into something morbid and terrifying. To that, you've succeeded to achieve that effect with me at least. Well done.
