Yeah, okay... when the credits section is so difficult to write, what can you expect from the game? Santa's Xmas Caper is not the most interesting game to end a year with, but somehow, it has the dubious honour of being a Christmas-themed game with the most conversions out there... or whatever. You already might have seen the Lazy Game Reviewer's video about this unfortunate little title, but since we're talking about two entirely different kinds of games with the same name (more or less), published by the same company, I don't really know whether this should have been a two-fer or not. But it's a Christmas special, so what the heck.
