We have Cave Story 2 at home

Pretty fun stealth game with characters from Cave Story, I like that it makes use of Santa’s name that’s kinda funny.
It’s a good time waster and 100%ing it can add some replay-ability, and at the low low price of free you can’t really go wrong.
Plus good Christmas games are a dime a dozen, I can see this being fun to play with friends around the holiday season.
