This was a lot of fun. i played it a few times. it would be nice if i could click the mouse to throw the snowballs, instead of space. nice graphics. nice upgrade. i liked how the player constantly said things like 'i can do this' or 'i have that' to let me know what to do.
also, minor bugs that i saw:
sometimes hitting space brought me back to the first room. sometimes, that brought snowmen with me (if they were hitting me)
if 2 snowmen were on top of eachother when one died, they both disappeared. but the other one could still attack and take damage (while invisible)
