Back to some game development this week. Had a good break over Christmas and recharged my batteries somewhat. Actually played some games for a bit, rather than coding!
The player energy (hit points) system is now in place. There will be a 'hardcore' mode for purists, allowing the energy bar to be switched off. In the standard mode, the player will be able to take 3-4 shots and firing continuously will also deplete the shields, hopefully encouraging more measured firing.
Enemies also have hit points allowing for tough bosses. The first boss now swoops down and attacks when the music hits certain key points. It's quite evil.
I'll try to get a point where another video can be uploaded next week.
