I was able to play your game by installing the required Unity version, but please the next time include a build and if it's possible a web build to play it on the browser.

Now about the game:

• I miss having a background music, it really adds to the atmosphere of a game so consider adding music in the future.
• I like the art of the character, even though there is some jittering when walking
• I think there's a bug in which you can win without collecting all the required cups
• I am not sure as how this game fits the theme, but as this is not a requirement it's okay

Overall it's a fine and simple game, which can improve a lot. Keep it up participating in game jams, it's also cool that you included the source code.
