I’ve been testing it and the vibration feels fine, no worries. In the end, everyone will tell you something different; I even saw static NPCs right at the beginning.
I’m not exactly sure what you mean by “Completion % mechanic.”
Overall, I like the idea quite a lot. The reward feeling from solving puzzles works well and makes you want to keep progressing. That said, I still feel like it needs a lot more progress and polish.
It would probably help to reinforce some aspects of the core loop: adding effects or sounds to movement, a slight camera shake in certain moments, etc. Coins, for example, should definitely make a sound when picked up.
It would also help if the different areas were a bit more visually distinct, so the player doesn’t have to stress their brain too much while navigating and can quickly recognize places they’ve already been to.
The concept is already fairly broad and honestly not bad at all; it just needs more polish.

You don’t need to try anything of mine, don’t worry.
