Yes I was planning to add more enemies, but due to a last minute crash I lost 3 hours of work (I am a dumbo who doesn't save), and had to do an all-nighter just to finish it before the deadline. I even had this idea of some moles playing golf, and you had to hit them before they take their hole-in-one shot. But didn't have the time.
I am planning to add these and more to the game later.
Thanks for the feedback.
