The game design and level design is not bad.
However, I do think you should increase the field of view.
Especially for puzzle platformers, the player receives information from the view, so you don't want the view too small.
Thank you for your feedback, it is important cuz I actually was struggling with level design and camera fov, so I know now I could make it bigger. There was also an idea that upon clicking a button it would show you whole level so you could actually see what's happening. But thank you for this feedback :>> and I'm glad you liked the level design :>
