Controls felt weird on mouse and keyboard since the layout makes it difficult to move the camera with the mouse and control the character with arrows and z / c. I would recommend changing this to a more traditional WASD / Space to jump / E to unload layout.
Nice work on integrating controller support , which felt more natural. The camera controls however still felt rather stiff and were inverted (tilting right moved the camera left, and vice versa).
I liked the bright, colorful graphics! The models and textures really invoked an old N64 style. I would find a nice cartoony skybox to drop in the game to tie it together a bit more. I enjoyed the different colored zones for each fruit type. The map looked nice.
I'm not a huge fan of limiting player mobility in a 3d platformer. I understand the concept of reducing the ability to jump as you pick up stuff, but I feel that the entire key to a good platformer is the movement, so it should only be restricted if it benefits the gameplay in some way or forces interesting decision making.
Overall, for only giving yourself a week, this was pretty neat! You have a solid graphical style going and fixes to the control layout and camera shouldn't require too much effort to polish this up! Then you can experiment with more level design / gameplay elements. Good work! :)
