they're not bad, they're just so damn mediocre
none of the levels are memorable, they're just a series of easy as shit segments grouped together
the game is super easy, aside from a few really hard parts that are only hard because they have some annoying gimmick associated with them - motion controls, comets etc.
and making you beat the game twice to see the real ending is an actual war crime
Pathologic makes you bet the game three times, and it's the best game that has ever existed.
