Perhaps I missed something, but when I first played this when you initially submitted, there was only the first "mode" with swatting the fly. Playing it again and having it switch to a more moody/dark game was quite a difference and I loved it. Wish there was more, especially because of that switch up. :)

I liked that the moods were a bit over the place in the right way. First it might look a bit like crude comedy, and then it gets kinda creepy and scary afterwards, it was a fun mix. Also, minor and fairly subjective, but I found the title screen to be particularly catching. Very minimalistic but oddly satisfying.
