Sidecucked (it's a zip file now)

You and your partner struggle for dominance and recognition as you dodge lava and floating blocks. Watch your back! Even superheros fall to the bullet, and the only thing that can stop it is your forcefield.

It is unknown why the city recognizes you as heros; all you do is shoot each other and run into lava.

Up/W - Jump

Down/S - Duck
