Thanks for liking our game! By the time we made the game, we just wanted players to explore the infinite combinations of the music samples and enjoy the first few minutes of the game. So, there is really no end of the game for now.
But now, we have the idea of adding a challenge mode. The curret game mode will be the free mode, where the player needs to level up and collect different samples in different universe. When they are satisfied with their music, enter the challenge mode to survive waves with much steeper difficulty until they die or destroy the enemy flagship.
