What would happen to the seasons if the tilt were less than 23.5 degrees and what would happen if it were greater

Because seasons are caused by the changing angles that sunlight strikes the Earth (due to it's tilted axis), a decrease in tilt  would mean less extreme seasons. Spring and fall are not affected by tilt because they are at the point in orbit where sunlight is hitting the earth evenly
