Nice idea and a good direction for the pixel art, though as others have said it doesn't look quite right when the pixels are all different sizes, the game art doesn't end up looking very consistent though every individual piece is well-designed. The music was also nice and the game could be really fun! I think the freeze mechanic works well here!
I couldn't really play the game however because the tutorial dialogue would constantly fire up on restart whilst enemies could already come and interfere with me and the timer already went down.This happened so quickly that I could never even really figure out how to deliver gifts at all. I did have a score of one but it didn't show in the end-game screen.
