I just gave a try in my phone, work well! Will be cool if the shells would appears randomly.
Anyway good work!
Do someone know how I can handle accented characters in dialogs? as my game will be in French too I got some issues with accents:
In the image above the sentence is "Vous avez trouvé une clef !", as you can see the character é is missing.
Using the html code instead of plain é doesn't work. Neither with unicode.
Let me now if you think about a solution!
