Like for a game that is already very eye-straining, given the constant motion and bright colours, why do so many creators make levels with such extreme strobe lights? Like for example all those Nine Circles levels that are probably not even pleasant to play because of the strobe effects during the wave sections. I know it's most likely a tactic to augment the level difficulty, but it can't be very good for your retinas and your vision as a whole and no pair of gaming glasses is gonna stop that. I know you can just not play these levels, but it gives you a good glimpse of what the GD community is like to itself and outsiders.
