Not bad for a first project, everyone has to start somewhere and this seems pretty good considering your experience, the art and title page are especially stand out as looking pretty decent. The lack of music and especially sound effects is quite noticeable however, even some basic sound effects would have improved the feel of the game a lot. I would also reccomend being a bit more unique in your next project, copying is a good way to learn but trying even one new thing a project, even if you fail, can improve your speed of learning dramatically. I've been in your position before and know how slow and hard development can seem at times but keeping at it and trying new things always seems the best approach. Best of Luck in the future!
