This was cute! I'm a fan of the low-poly 3D artstyle and music, definitely did well with the cozy vibes. I appreciate that this was a straightforward and easily-digestible concept--I can tell you all were able to polish it quite a bit as a result of keeping the scope reasonable for a 3-day jam.
If there were time to make this a bit more fleshed out, I would recommend a bit more variety in how you actually acquire the mittens. Maybe different kinds of minigames, or some way of incorporating the environment into the challenge.
Overall very wintery, very cozy. Well done!
