Interesting concept for a game! I liked the gameshow vibe and the overall feel of the game.
If you wanted to improve, I suggest showing images of the items your looking for either at the beginning before the level or by hovering over the words. I also suggest giving each object a rotation to jump to when picked up, I had a lot of trouble finding the knife and even picked it up before but didn't recognize it as it wasn't on the small edge. Lastly, I suggest playing into the game show theme more and making up some prize for the player based upon how far they got instead of just going to an end menu. You could even make it a little system where you keep playing the game show trying to get objects or skins for your character.
Overall neat concept! Check out my game if you get a chance!
