For a two-day submission this is good fun. The idea to play as an elf who reluctantly is forced to bowl using the bodies of his elf friends as pins is a devilishly evil one! I guess Christmas isn't gonna be so merry after all...
Given the context the game was made in, constructive criticism seems a bit unnecessary, but the bowling would have been a little more interesting and uncertain with some basic physics/spin or a quicker bowling speed. Also, I did find the secret skeleton in the bottom left of the alley!
