Don't know what you talking about, I had fun on the third level where you have to trap the monster in a sort of a cage. You actually managed to make decent music and a properly working reset, which I failed to do in my project.
Also, you created two different types of enemies, you already can build some interesting levels with those two.
Finally if you simplify the art, you will get a really decent experience out of this(use basic shapes like rectangles or triangles when you don't have time)
Great job, keep it up.
