So I just had this crazy idea for a game.
It would require stereo speakers.
So you're this white dot thingy. And there are enemies coming toward you. And you can't see them at all. But there are two different walls ahead of you that form a path that the enemies travel through. The enemies bounce against the walls. When an enemy hits the left wall, it makes one sound, and when it hits the right wall, it makes a different sound. The panning of the sound is based on the horizontal position of the enemy, and the volume is based on the distance.
And you have to use that information to avoid the enemies.
Ehhh?
Hey Tesselode!
I always see you tossing around those ideas, and I like it! But I think this one has been done quite professionally on the Gameboy Advance by the "Bit Generations" collection, which is basically an indie collectible game collection for the GBA, which I cannot recommend highly enough!
Obviously that shouldn't deter you, not at all! But maybe you can have a look and see how they did it. Some of these games made me hopelessly addicted a while back. Also their packaging is beautiful.
