My son has been asking me to make him a game, and he's even drawn me some pictures, which have been converted to sprites. So I thought I'd use the jam to come up with a titlescreen.
My plan is to have a knight jumping through the screen, and slashing it with his sword. Here's some rough SVG to define some shape at the three phases of animation. I haven't worked with affine sprites on the GBA yet, but I'll have a look so I can zoom him in.
I've not had too much time to work on it so far, but hopefully working with some rough graphics to get the flow right first is the best way of doing it.
