This game gives me mixed feelings because it's suppose to commemorate the previous 4 games as you literally go through the worlds of the previous 4 games but it feels watered down due to fitting too much and not having enough space due to limitations? Also the whole going through various portals can be tedious and basically plays like Kirby & the Amazing Mirror... There is a completion progress and in order to get 100% you will have to go through each stage/world and portals... Thankfully the battle modes is solid.
