Ah, thank you for playing. You can change sensitivity by pressing the escape button. Also, you could jump in the first one. There's quite a few secrets and other endings to find if you do.
And thank you for making it. I enjoy these surreal entries. I was iffy about ever hitting escape, since it ejected me from some games, heh. As for jumping, I may have forgotten since it's been a year. Will have to play the first again and explore more!
