Thanks for the feedback! I'm happy to hear you managed to complete the level.
Centering the camera makes sense, I'm looking into it. Possibly making the camera also a bit more above the character.
I understand the color of the player not being visually fair, I liked to have the same color palette for him as the rest of the game objects. I could make the colors more dark or have more contrast so the character is easier to see. Or have some particle effect surrounding the character which would make it more clear to see your character.
I didn't consider the feet having the possibility to stand in the air, I'm considering making the collision for the character smaller, making standing on objects visually more fair, that seems to fix it well for now.
