You definitely got me to feel the emotions that you intended in the chase sequence XD. The game was really fun! I liked how smoothly the red monster moved, the fact that the monster didn't seem to be moving like the rest of the world added to the sense of uncannyness.
Fun fact: You can actually go faster if you move diagonally, because the speeds of you moving sideways and you going forwards are added together. I personally enjoyed that quirk of the movement in the game, because it added more depth to running away, but if you want to disable it in future games you can "normalize" your movement.
