Yeah, it would act like toaster, but with bigger spread. I thought the powered version could have the projectiles stick around on the walls/floor for a while, along with a slighty longer range.

Anyway, I just had some ideas regarding sprite rotaion.

How about the players sprite rotating if they go on a slope? This would also influence the direction they shoot in. (lets stay, if you were running up 45 degree slope, you'd be shooting in that direction too).

I think seekers could rotate smoothly instead of using the 45 degree sprites, which looks kinda jerky.
