I did something similar for my own submission, but in a different genre; it's interesting to reflect on the concept from another angle. I liked that the controls are always very legible and consistent in their positions relative to each other, even as their shared position on the keyboard moves around. I wanted some warning that the controls were going to change. Without that, it's mostly frustrating when it causes a failure.
I'm intrigued by the tilt mechanic, especially because that's the name of the game. In practice I never triggered it. I did it intentionally just to see what would happen, and I found the loss of control interesting (and thematically appropriate), but I'm not sure platformer is the right genre for it. There's not enough going on at one time to inspire frantic inputs that might lead to tilt, and if there were, it would mean the situation was already overwhelming, so the tilt would only aggravate that. It might be better to rethink it as a way of punishing reckless action, or something like that.
Anyway, nice work completing your project, and thanks for sharing!
