In a large mixing bowl, combine the corn, jalapeños, red onion, and red bell pepper. Add the blueberries and chopped cilantro, followed by the sea salt and sugar. Squeeze in the fresh lime juice and gently toss everything together until the mixture is evenly coated and vibrant in color.

For serving, transfer the salsa to a wide bowl or platter. Pair with crispy tortilla chips or layer it over nachos for a colorful and flavorful snack or appetizer. Serve immediately or chill briefly to let the flavors meld.
