So i was wondering if anyone would post their ideas for a 3D Platformer/Twin-Stick Shooter. i'm developing. Please, i need ideas. I already have some but i need more like features. It kinda gonna be like Assault Android Cactus.

I've thought about doing a reverse on the zombie type game, where you play as the zombie and try to increase your brain power, as you get smarter you learn to use weapons and such. There would even be a chance to turn back into a human. Just an idea.
