The game I have in mind for this is a simple visual novel type-game that would only have a few scenes, a menu, and a gameplay scene (possibly menu). There will be no moving pictures or whatever, only text. Kinda like the game Lifeline.
And, because theres only 2 -3 scenes, there wont be many images, so the file size would be relatively low.
So this should work, right? I would use Adobe PhoneGap (or something similar) to compile it into an app.
EDIT: No idea why it made more than one of this post! Weird...
