Planet Robobot is easily the best entry in the series so far. A lot of the other games have gimmicks that can be a little iffy at times or a need for collectibles to progress or unlock somethings, but luckily the gimmick of the game is perfect and the amount of collectibles you need is minimal and they're easy to find. The Robobot is a lot of fun to use and the Copy Abilities are fun to use with it. The new abilities are really fun, especially ESP which is one of my personal favourites. The level design is also the best here, with really great gimmicks, scenery, and the auto-scrollers are actually not bad (if you didn't know, I hate auto-scroller levels). I guess really the only thing I could think of for a complaint is the long final bosses, but I actually loved those because I really like boss fights in video games and these were pretty well made, so not a real issue for me just something others may not like. Overall, Planet Robobot is an excellent Kirby game in terms of level design and gimmicks and is easily my favourite at the moment.
