An unfinished mess but what IS here is pretty good, for the most part! The soundtrack is amazing and graphics are very cartoonish and stylized, gameplay also feels smooth after you get the hang of it. Unfortunately, there are LOTS of bugs present here and also the game's very short, 100%ting Twinsanity takes about 4 hours on a first time playthrough if you're good at platformers. I'd say the bugs add to the silly charm of the game, makes it even funnier to play, but it isn't for everyone, though.
