The Intro: The story in the start is nice way to give context for the game but, the font is hard to read and the story is to long, I had skipped it the first time I played it. I would put the story in different parts of the map for players to find and read on their own.
Art: I don’t mind the pixel art style for a game like this but, feel that the background and the stage sprites don’t work well together. IMO, I would go with a blockier style for all the art in the game.
Gameplay: I don’t think having Infinite jumps is good for the game, it causes bugs like clipping. I saw that stairs in the game not made to fit the sprite. The camera makes it hard to see the upcoming hazards, I feel that the camera should be focused on the stage rather than the character. To give an example, NES Mario's camera would be my suggestion of how to do the camera.
Items: The ships parts in the game don’t seem to have any purpose right now, but I think it would be cool to have it so that you complete all the levels without getting any or some of the ship parts but get a bad ending, but getting all the parts gets the layer a good ending. The food is fine to have in the game, but I feel that there should be more of it placed in the level or they should give back more bar.
