I mean for the most part I enjoyed the regular bonus levels, some of them could be a bit harsh but I’d say most of it was on the fair/not horribly annoying side (the stage where you have to light all the torches over poison water and spinning platforms to get the stars is the exception). I wouldn’t consider them necessary but I thought they actually served their purpose rather well. It’s just that bit at the very end took a rather huge/sudden leap from “tough but reasonable” to “go fuck yourself”.
