Overall nice game :) I like those "River City Ransom" style games.
Although you didn't had much time, the gameplay itself is really solid and feels bugfree.
I think there should be an indication about touching enemies in the y-direction, e.g. a shadow ellipse like @renato_grottesi 's comment suggested. I lost a lot of health because of it even though I didn't noticed.
Music and sfx are nice, but sometimes there seems to be sfx missing (e.g. bow, enemies)
I had the same issue like @renato_grottesi with the speed of the text boxes, I couldn't read it all in time.
I liked the text that showed up on the middle door :D Don't want to spoiler it for others.
