The thing is: the levels of Star Allies totally lack of the creativity of pretty much all of the previous entries. I mean, think about the Great Cave Offensive from Super Star Ultra, or the Circus levels of Triple Deluxe or the casino levels of Planet Robobot for instance. This game doesn’t have anything like that (the closest one to that is Planet Towara, incidentally my favorite level in the game). The mechanics with the group are not funny as the Super Abilities, the Hypernova or the Robobot Armors, very often those mechanics are reduced to just “jump at the right moment” (the train one is the worst offender as that’s a moment in which the game REALLY play itself: you just have to jump ONCE at the very end of it. The collectibles are also insultingly placed here. Not only there are way less than in previous entries, but also they’re placed IN THE MIDDLE OF THE STAGE and not in secret doors with puzzles that require a specific move of a specific ability to get them (there are really few things like that in this game, mostly the switches that unlock secret levels). Also, due to the friends mechanic, bosses are even easier than before. You start a fight and then it’s over in less of 30 seconds. Also as you pointed, not only the game gives you HUNDREDS of extra lifes, but also unlike in the previous games in which the counter is always resetted when you restart reset the game, in this one the counter is saved for its enterity even when you reset.
There’s no point in focusing in this game: you almost can’t die, the collectibles are mostly thrown right in your face and the bosses are always over in seconds. The only cool things of this game are the final boss, the hardest modes of the Boss Rush, and the extra mode, which actually requires A LOT of focus to get all the hearts and the best ending. The main campaign is just poor from every point of view, and lacks of the soul that previous Kirby games always add.
