I really liked the parts where you go off-screen and the level where gravity appears.
In the off-screen section, I enjoyed how you have to track your position by watching the monster’s movements.
And in the gravity level, it was terrifying — when you accidentally fall into the pit on the right and the monster comes after you, there’s absolutely nothing you can do!
The monster’s design is wonderfully horrifying, but I felt a bit sad that it looked so small while chasing me — I couldn’t quite see what it really looked like.
...But as I was writing this, I reached the stage right before the final one, and there it was — a big, clear image of the monster!
That stage felt like escaping from rising lava, which was really cool
