I have to say that for a "very newbie gamedev" your art style and animation is impressive. I love the cartoon style of the bat and monsters. On the gameplay side of things, I enjoyed the strategy of having to lure the monsters away from the button at the end in order to press it. I think adding a sort of attack or dash would make it a lot more interactive and interesting, but I think it turned out great anyways! Keep up the good work :)
