Yes

Summarise your game!
2D pixel platformer where the player controls a scientist who flings his own body (press [A]) into hordes of knife shaped zombies in order to heal them - by drenching them in blood.
The healed knombies are transformed back into their original human form. Because the scientist's body is hurt every time he hits a knife, he has to be healed by getting new blood from the nearby blood transfusion (press [S]).
Try to survive all 4 waves!

Please explain how your game fits the theme:
The theme is "You Are The Weapon", so I took this very literally and expanded from there. My very first idea was the human-wielding sword which is also depicted as a sketch in my GDD. But this didn't look and feel right (I even made some animations with this). A friend remarked that the one of the inverted sword/human animations looked like the human was bouncing on a pogo stick. That's how the whole idea came to be.
Thanks for an awesome second game jam for me!
