Thank you so much for such detailed feedback! I really appreciate it, it will help me with future development.
The mute button actually only turns off the melody in the levels. This was the original idea, as I wanted to keep the game's natural sounds, but also have the option to play without the background melody (if it suddenly becomes annoying).
In the future, I might implement the ability to turn off sounds as well.
Actually, I was planning on making cutscenes (similar to the intro), but not after every level, but maybe once in 2-3 levels. I planned to make the first levels more educational and revealing of the mechanics.
Thank you for emphasizing this, it really is important to implement in the future.
Please tell me if you had any difficulties understanding the hints, finding items, or understanding where and how the level ends?
