I nearly didn't buy this game because of the meme reviews you see in the positive category. It didn't help that "Overwhelmingly Positive" reviewed games are often one note and memey trash. I saw some gameplay though and a friend recommended it. The game is a mixture of old Sonic and Wario Land Shake It. If you have experience with either, you'll know what this game is before playing it.
Near impossible to lose levels where the challenge comes from scoring high to get max rank. The first half of all levels except one give the player zero difficulty unless he wants a good score, the second half gives him a very generous timer for leaving the level to beat it. In order to progress through the game you will need to find pick-ups in each level that are easy enough locate and Google is always there if you're lost. The game is incredibly easy if you don't care about score. The worst players would only find one level a struggle to beat and I guess the second boss too.
The game is only worth the money and time if you want to get the highscores. It's just too easy to reward the time investment, even with the animations, music shifts, and overall character of the game. I can only recommend it if you take the challenge to get max rank in every level. Getting the P rank is what's rewarding in this game and makes the music and character of it better.
Getting the max rank will require finding every important pick-up, secret room, and looping the level's second half all while maintaining one score combo that starts with your first kill and is extended by more kills and pick-ups. These challenges are difficult, fair, and worth even full price. If all you want though is to breeze through then I think you'll be better off watching a streamer play.
