I am working on stories first part in my game. It is a mini-game that you see after running away from computer. You fall down in a computer inspired environment, and there is enemies & platforms for you to keep away. I was looking at moving backgrounds. I'm moving them on z-axis (from +z to -z), like they are coming towards screen. They have a constant speed. There is a black main background with white highlights that look like you enter a dark room and someone opens lights. And then backgrounds start spawning and moving towards screen. Character will move left-right via accelerometer, and if a platform hits you (they have different features, breakable, non-breakable), you are pushed back. If you are in dead zone for a few seconds, you restart. That is how this level works. (I recorded a little video of moving backgrounds, sorry for low quality.) At the actual game, I'm thinking about putting a prompt to say user, "Hold your device parallel to ground, so experience gets better.", at the start of this level. But I'm unsure, is it a good way to tell user to get a specific position for each level? (I am going to use this for one level for now, but what if I make more levels like this?) Maybe there is a way to give this falling effect to the user, more effectively. Do you have an idea? PS. There is gold-ish colored lights on 4 directions. I make them to look like lights that is hitting on walls, but it looks like Camera is dirty... Do you think that needs improvements too, or is it good this way?
