Honestly impressive! :o
Apart from Narrative, you scored everything perfectly: the game is creative, enjoyable, the visuals are incredible (the swallowing effect, the use of dynamic colours to help the player see what to eat and what to dodge, the old screen effect)...
Easy to understand at a glance, the controls work perfectly, I can't find any negatives: for a game jam entry, you did very well!
And since you named your game after Shi-fu-mi... Excellent travail à l'équipe, franchement bravo ! =D
