I love the space theme, with the astronaut character and alien enemies. All of the art is amazing but the background and animations caught my eye the most. The implementation of multiple levels made the game more challenging. Certain levels, such as the one with a narrow path covered in spikes, were especially difficult but fun nonetheless because I had to maneuver and time my player movement expertly. One suggestion I have is to add a limited number of lives to make it even more challenging. And once the player runs out of lives, they will restart at level 1.
