Thank you for your suggestion! I'm glad you had fun playing the game! I had originally planned to add more obstacles like spikes, UFO rays from the skies, aliens blasting from the other side of the screen, and interactable objects that could lead to death or rewards (chance-based system). The main problem I had, while thinking of the obstacles, was thinking of counterplays to the obstacles, because if I don't make counterplays, people might find the game frustrating to play instead of fun. When I have time, I'll update the game and add more obstacles (and maybe add some lore) :)
