This is a weird sequel:

the first game was a very actiony metroidvania, with the map being generally small and linear. this time, the map is much bigger, having 2 different worlds to traverse through, and traversal is the main gameplay loop here. they made the main gameplay loop a puzzle of traversal, figuring out where to go, moving around both dimensions to find new stuff. that also allowed them to build the story a lot more than the first game, this is a major step in presentation......

and then they forgot to add bosses, or make the combat engaging like in the first game. seriously, this game is very much like ori 1, combat is incidental and inconsequential and there are no bosses beyond exactly 2 scripted story events that can barely be qualified as bosses.
