Overscoping is really a common thing in jam, so don't be too discouraged by it. The art is really nice, both the large cutscene images and the character and enemy sprites. Though gameplay is lacking right now, I think the idea looks intriguing, and I am really curious how the game would play if it's done.
I'd normally do my usual compliment + suggestion section, but I don't think it's even helpful in this case. I'll hope this doesn't make you feel too bad, and keep making games!
