Nice game! I wasn't sure if the mittens were strategically hid around the level or if they just had a chance to randomly pop up when you make a snow angel. The snow angel mini game was too fast sometimes, I liked that it was variable, but the minimum time threshold needed to be a little higher.
If the mittens do randomly spawn, then I would've liked to see them hidden around the level in certain spots maybe near terrain and markers.
Overall very nice presentation. The art/overall look was great and clean!
