That's really good feedback. Based on your feedback, I have to focus on level design. I used 3 different scenes with two doors each. Unintended colliders are invisible walls and floors.
Sometimes there is an audio bug. When I went to the shop and went out, and suddenly clicked the shop again, the click sound played, but I didn't go into the shop. It happens somethings, not always!
But the rest are perfect! Art, music, sound, gameplay and all are perfect! 11/10
