Cute game, the objective of using the lemons to trade for ingredients, interact with the characters, and find the multiple endings is pretty clear, though lacking intricacy. It's a shame you lost the files for the game, because it's off to a good start.
Your style has a pleasing sense of originality, and if you ever do decide to work on a remake, I would add medals for the different endings or possibly show which ones were collected so far as each are found. It would keep track of them a bit easier.
