Feels like Puyo Puyo's Sonic Jam moment. Great ports and oodles of new content. Lots of care was taken to retrofit mechanics and characters from later games into Tsuu's engine and art style. It's a real treat for fans and one of the best ways to play these games.

Edit: oh yeah there's also a whole rpg mode with an overworld and dungeons and it's better than the actual Puyo Puyo rpg released sixteen years later. Good stuff!
