While the game I've been bleating on about gets a theme, development has been hampered for the simple reason I'm an absolute novice at Flixel. (The more complicated reason involves job search.)
So I'm practising with a simple platform game that currently looks suspiciously similar to jmbt02's Achievement Unlocked.
I guess part of the problem is that I find the overall finished look of the game to be entangled with being able to develop the machinery. As I need to learn Flixel, a simple throwaway platformer should be safe enough for making mistakes on.
