The core idea is original and pretty fun, the graphic looks good.
Sadly, the game lacks balance and it seems to be pure luck whether you'll get enough melons or benches to be able to go further or not. You should work on that and try to find ways to make strategic decisions, for example you could keep the melons on you, but eating one of them would slow you down, so you would have to eat them at the right moment ?
Adding a small music would be a plus, as well as some basic instructions at the start.
Good work ! :)
