No point turning around now. Not as much progress as I hoped today but still far more than I would ever get done outside of a Ludum dare :).

Concept: You are stuck in a snowglobe and enemies form out of the snow to consume it, leaving less snow in the air after more enemies spawn. At the end of a stage, the snowglobe is shaken and all the snow from the dead enemies is put back up into the air to create more! Only one variety of enemy so far (angry snowman thing in the gif) but more definitely coming.
