A decent first effort, and congrats to the dev for realizing that small games allow a chance to learn without investing a lot of time in re-doing some elements of a bigger game.
Besides the text disappearing at the bottom of the page, the text box almost always hides the actual action in the scene. Next game, dev might want to just use closeups on the action being described, so that it appears in the center. Also, break up some of the paragraphs of text and put them on separate pages using the same image. That will allow the dev to reduce the size of the text boxes if they need to in order to show the action. It also helps the player maintain interest.
All in all, though, a very credible effort and I look forward to more from this developer.
