For your first game ever, this is a very exciting project. I like your choice for the assets and the sound effects. I liked the way the hero navigates through the levels. Frankly, I couldn't get beyond level 1. I was stuck a bit. I think the entry difficulty is a bit high. You might think of facilitating the first level in order to provide an easier entry level. Nonetheless, I am impressed with your first game. The fact that you finished a game of this size as your first project is a huge step. I am waiting for your second game in which you will use all the experience that you got from this one. Good Luck!
