Whilst working on animation support for Athena for Courage, I began working on a game for the iPhone called Catalyst last weekend.
I was thinking about a game I had played about a month or two before called Polygonal Fury, and realised it would port nicely onto the iPhone.
Since the collision of a circle is easy, they seems the easiest to setup for interaction with touching the screen.
All sprites within the game are triangle fans, but I will probably change them to quads with a texture due to the break that occasionally appears in the geometry, and alpha glow around the edge.
The background needs changing, I was thinking of something going on in the background like in another Flash game I played, Spewer, with maybe cut scenes like the Nintendo DS game Contact had.
