I'm glad you gave it a try. I will fix the issue you mentioned about the first hole. I ran out of time to implement a death trigger here.
The game is slightly easier when played with a controller (if you have one). You should be able to jump onto the blocks with a held jump. So, hold the jump button down fully and you will jump higher.
I do need to fix the watermelon slice and remove the rigidbody from it. I found it funny when testing but can see how it can get in the way.
These issues should be fixed tomorrow evening. Hopefully the fixes will allow you to get to the end.
