Nice little demo. I love the artwork and the movement is simple yet effective. I appreciate that you can use the dash infinitely to speed through the slower parts of each level. This can definitely turn into a speedrunner's game if you want it to be :)
Are there any bosses, objective, or side quests planned? I personally think having some kind of challenge or allure to discover something bigger about the world would make the player & knight's journey to see the sea all the more exciting.
