This is pretty impressive to create within a week (even with the assets you already had). Well done! Cool puzzles and well thought solutions. This has a lot of potential, keep it up! :D
Except for a few crashes, most of it seemed to work as I expected. Just maybe keep the controls limited. I think it’s fine if you pick up/use and throw with the same key (E), perhaps even pickup fruit with E as well, as that seemed to be the interaction control for most scenarios. I was also missing an instruction-text like everything else has for picking up fruit, I didn’t know that was a thing. I was stuck on the elevation level for so long :’)
Great potential though, amazing entry, well done :D
