Hi, I have several issues to report.
-First, there's a typo in the title, you wrote "Wondering knight" with an "o" instead of an "a" in the title screen and app file.
-Lateral movement when in the air is too high, pressing the left or right key once when falling or jumping causes a big lateral push.
-There seems to be blurry jitter on the player character when the camera follows him. You might wanna experiment with your character and camera updating, and maybe try all combinations of Update/FixedUpdate/LateUpdate.
-Jumping often does not trigger as expected, it seems that it has a cooldown whereas we're expecting to be able to spam jump in most plaftormers, and it apparently tends not to trigger when moving laterally
-I don't see any clear connection to the theme "Nothing can go wrong".
Despite all of this, you still made and published what seems to be your first project on itch, so this is definitely a start ! Good luck on your journey.
