This game has a really cool and interesting gimmick in the way you move kirby, which leads to a really enjoyable experience in some levels, but overall the game doesn't know what to do with itself. Many levels seem created to not let you have fun with the paintbrush system via strict design such as very linear and narrow paths and the game tends to get tedious (a good example but sadly not even close to the only one: the water levels. Also why are there so many). The abilities are hit or miss, with baloon, needle and burning in particular standing out as some of the best parts in the entire game and are severely underused , while the others are pretty meddling. The bosses try to take different approaches to stylus control but it never really works, and the minibosses all feel like a joke instead of genuine challenges.
Overall you could probably make a very fun game using this game's basic systems, but what we have right now doesn't even come close to its fullest potential.
