Wouldn't it be cool if the projectiles got life out/hit sprite animations? Or enemy death animations? Let me explain. If you shot a projectile and it was set (this feature is also a suggestion) so that the projectile get's destroyed on impact on any object, then it should play an animation. Or if an enemy was killed, you jump on it, and it plays an animation. I would be happy to create these sprites, but will Ting Thing decide to do this? I think this would improve PB's reception. As most of our suggestions do.
