An Informative Concept Drawing

My plan is to make a game where the player controls a flock* of ninjas with various abilities presented with the following task: Kill everything on screen and get off-screen within 10 seconds. The ninjas will be controlled via a timeline, so everything’s planned ahead of time and can be controlled very precisely (because these are ninjas – no mortal can hope to control a flock of them at the same time!). I’m hoping that this will lead to interesting (and difficult to program!) possibilities for level design (though I wish “level design” weren’t a thing I had to say) – like having two enemies be in planes and having a single rock thrown at them strike both if they’re in a line above the ninja, which they will be for only a brief instant (i.e. enough for a ninja).

Besides, I’ve already done the hardest part for this idea of a game: I’ve named it in a “clever” way!

*I believe this is the technical term
