As my husband commented, the first thing that really stands out to me is calling it a point and click game, but requiring both keyboard and mouse. Having keyboard as an additional option is okay, but you should be able to play a point and click game with just the mouse. The keyboard keys weren’t very intuitive either. While using space made sense, I wouldn’t have thought to use E without being told to.
It was good that you had text show up when you moused over something you could interact with, though I think it would have also been helpful if you had highlighted the object as well. The collision shapes didn’t always seem to match what it looked like it should have. For example, in some mouse positions, the text said ‘watermelon’ but the image and the dialog were the peanuts.
The game itself was also lacking any real direction. I clicked around, but it was very unclear what was and what wasn’t important. I still genuinely don’t know what I did to make the other two items appear. Combining items was awkward and clunky. Sometimes combining items would give you some dialog while you kept the item you first picked up, sometimes it would give you dialog and have you drop the item you picked up, sometimes it wouldn’t give you dialog and have you drop the item you picked up, and sometimes it wouldn’t give you dialog and would swap what item you were holding. Having dialog for each combination, even something as simple as “those things don’t go together”. would have been helpful.
My biggest recommendation would be to give more feedback to the player, and have that feedback be consistent. That will help the player feel like they are actually accomplishing things.
