I love the art, animations, overall vibe, and the game mechanics are pretty interesting. It definitely created that sense of urgency with the weird wall chasing you, having to always be aware of where your mouse is, and having to type the letters as they come up, all while navigating through some pretty challenging platforming. I like what you're going for here, and man oh man was it HARD.
That being said, there were some things that I feel did a disservice to an otherwise great idea. Some levels had some really cheap traps, the kind that you would never have a clue were traps until you run into it. That sort of thing is never fun, it just invokes a response of like, "seriously?" and this happened quite a few times. The ropes were also a bit finicky, and with how you have to use your mouse to use the ropes and with how fast they throw you, it's really easy to get thrown past your mouse and now you're looking backwards. Also I'm not sure if the sticking to walls was intentional or not, but it was more often frustrating than useful.
All in all, good game!
