Tak 2 is a monumentally better game than the original Tak for a multitude of reasons: Better jump physics, dialogue, less I-Frame issues, the list could go on. I would argue there are a few too many difficulty spikes for a kids game, but maybe the kids enjoyed that sort of thing. I can assure y'all I was not a fan. The animal puzzles always stumped me as a kid, haha.
I still think this game is pretty darn good, and I know a remaster would never happen, i think it would be darn amazing to see this little rat of a man in HD
