The base puzzles you have to complete are decent. The bonus stars, however, aren't. They seem to be less puzzle solving and more hide and seek, making sure you explore every single nook and cranny of the worlds, even though most lead to nothing. The levels are too large and represent just a massive area to search with no actual added content, just map size. Honestly, if you plan to do the bonus stars, just use a guide, don't bash your head against the wall trying to decipher esoteric bs or looking for a needle in a haystack.
