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.

Does anyone want to provide more feedback?

Hello!
I played for a bit, and was quite confused as to what i had to do to start, but eventually i started figuring out I have to collect keys and complete puzzles.

Screen shake seemed fine to me. I see the completion goes up with every coin and key i collect - but i dont really have anything to say about that. I know for myself, i wouldn't never even try to collect all the coins. I see NPCs, but i dont really know how to interact with them so i ignored them.
Lastly, the music was a bit brutal on the ears, so i turned it off.

I'd welcome feedback on my project. Mostly about how fun it is.
