What I liked:
- The aesthetics and sound remind me of old arcade games. Makes me a bit nostalgic.
- The puzzle idea has some really cool potential and you already used it pretty well here.
- You kept the game small but enjoyable.
Suggestions:
- I think you should be more clear to the player about how the puzzle mechanics work in the beginning. You do fine with giving necessary explanation when needed like moving food, but it took me longer than it should have to figure out the mechanics.
Congratulations on your completing and submitting your game!
