It was more like the opposite (the game started out goreless and I added the option to turn it on for people that think pulping enemies is awesome), but you have a point.
Viewing post in small graphical inconsistency (almost fixed)
An addendum on the "add obstacles instead" option not being indicated enough: when you go to change the in-game description to mention that it can be either extra platforms OR extra obstacles, please replace "no help" with something less specific like "no change" to make it extra clear that the option isn't just for more help.
Stumbled across a new one just now: if you rocket-boost into a concave ceiling corner in just the right way, you can get stuck forever.

EDIT: Oh, and for completeness' sake, I figured I'd also mention this other, less severe glitch I encountered while trying to recreate the previous one: rocket-boosting into a convex ceiling corner can cause the rocket to hang, but this one is much easier to escape from.
