Day 1 (Monday)
I started my game today, as I wanted to spend Sunday with my daughter. The late start let me spend some time thinking about what game idea to do. I've ended up committing to the idea of a space shooter. I think the genre is not very fresh, but it does provide a good test bed to develop game engine technology.
So far I've created a ship you can fly around with the joystick, and AI enemies that swarm and attack, and which you can shoot. They come in never-ending waves.
