This is exactly what a sequel to a mere puzzle game should be- The upgrades fix the monotony of the first game while bringing character and charm to new assets. The story enhances the previous entry's narrative and expands the world, the mechanics are not made any more complex for no reason, but different characters having different stats is a fun way to make the gameplay fresh compared to the unchanging stats of the original. It's extremely innovative and references other Taito games that aren't there for marketing purposes, but just for fun. With pleasing new artwork and characters, this truly is a game with a lot of fun potential and character that makes it a great sequel. Also, dinosaurs. Rawr.
