So I decided to start a new serious game project; lately I’ve just been tinkering around with random concepts without a cohesive game with which I can put a real bit of gameplay. So, today, I started a project that has a little green guy who can shoot an enemy that will bite when you come near and an enemy that can fly around and he’ll freeze and turn into a platform when you press his button (or die if you shoot him). It’s playable at this point, and darn near complete in what it does; it’s not really buggy, and all of the elements that I currently have in it, like the enemies, are pretty well-polished. Obviously, though, there isn’t much of a game there, so I’m going to have to expand. The main issue, however, is that I don’t really have a main mechanic to build the game on… Right now it’s just another mindless platform shooter. I’d like to keep the level design from getting too intense with puzzle elements, but I also want to keep things interesting. Any ideas?
Note: It will be iPhone compatible, so no crazy button-frenzy controls! I want it to have the player only ever use left, right, jump, and shoot buttons, which will be placed in a static position on the screen. Beyond that, it has to be something that at least isn’t used frequently like jump or shoot; a power-up activation button or something would be okay.
